Dancing With the Stars
returns on Monday with Most Memorable Year Week, and according to the celebrities, there's sure to be plenty of emotions running wild in the ballroom.

The stars each got to handpick a song that represents a "truly incredible experience in their life," a story they'll tell through their partner's choreography.

Ahead of their highly anticipated performances, ET's breaking down everything you need to know!

Who's on top of the leaderboard?

1. Normani Kordei and Val Chmerkovskiy: 34/40
2. Tie! Heather Morris and Maksim Chmerkovskiy/Alan Bersten, and Nancy Kerrigan and Artem Chigvintsev: 33/40
3. Simone Biles and Sasha Farber: 32/40

Who's in danger of elimination?

Mr. T and Kym Herjavec and Bonner Bolton and Sharna Burgess both received the lowest scores from the judges last week -- 24/40. But #TeamDenimNDiamonds has been a fan favorite all season, so we know their fans will pull through and keep them safe! #TeamDancingFools, however, may not be so lucky. We're guessing Monday will be Mr. T's last chance to dance on the show.

Close behind them, #TeamBabyGotBach, Nick Viall and Peta Murgatroyd, and #TeamPrettyXxpensive, Erika Jayne and Gleb Savchenko, who both scored 26 points last week.

"I'm always looking to get better, right? So regardless of what the judges say, as long as I'm still here, I'm going to try to get better and hopefully I will and still enjoy this experience," said Viall, who will be dancing a rumba to Ed Sheeran's "Shape of You," which he's dedicating to his fiancée, Vanessa Grimaldi.

Bonner Bolton and Sharna Burgess are reflecting on the professional bull rider's near-fatal accident.

It's a new dawn, it's a new day, it's a new life for Bonner, who will be dancing the foxtrot to "Feeling Good" by Michael Bublé.

Sharna's choreography is sure to be spectacular, as she'll attempt to help Bonner tell his story of the time he was paralyzed from a C-2 fracture broken neck after her was bucked off the back of a bull last January. Currently, Bonner's not able to ride at the request of PBR, and his parents, because if he were to get whipped the wrong way again, it could kill him.

"[When] I talked to Bonner about our most memorable year idea that I have and how I want to tell his story, he did tear up, he did actually have tears streaming down his face, and I want people to see that part of him," the red-headed beauty told ET during a Facebook Live interview following their Charleston last week. "I think we see the sexy side, the all-American tough cowboy, but I think we need to see the very real side that's been through some hardship."

"There's a very real thing -- he's had to leave what he loves most in this world, and I think we need to get to know that side now, the depth, instead of just, 'Are Bonner and Sharna in a relationship?'" she added. "I love telling stories and most memorable is one of my favorite weeks to talk about and create. I'm a big fan of showing [the audience] who that person was before, that adversity, and showing who they are now, that transition, within the number. I have this amazing, crazy idea, and I'm hoping they let me do it!"

So what types of movements can we expect from Bonner on Monday? Sharna gave us some teasers!

"I want him to have this dance therapy moment where his former self, his bull-riding self, sort of tips his hat and accepts and says, 'You've got this now,' and moves on to this next stage of his life that doesn't really involve bull riding," she explained. "Because as much as he wants to go back to it, I don't know if that's ever going to be a possibility for him. He has to accept this new life he has to live."

"It's very different to anything his family's ever done, and it's very different to anything I'm sure he ever thought he'd do," she continued. "I think it's heartbreaking for him, [but] at the same time exciting."

James Hinchliffe has some advice for Bonner: "Smile!"

ET also caught up with Sharna's season 23 partner, James Hinchcliffe, last week, who talked about the importance of Most Memorable Year Week. Like Bonner, he suffered a near-fatal accident when his car crashed during a practice race for the Indy 500 in 2015.

"Last season when we got to this point, what Sharna told me was, 'This week is about you. You're dancing for you,'" he dished. "And it was a little bit of a turning point for me because you are telling part of your own story. I'm similar to Bonner in a lot of ways -- I come from sport, I had an injury, there are a lot of similarities there. And I get how weird and foreign this whole experience is."

"But this week for me last year was kind of that real turning point, where I really started to kind of enjoy dance and enjoy dancing for a reason," he continued, telling ET his advice for Bonner is to "tap into whatever his most memorable year is" and "really kind of let go and enjoy it."

"And being able to make fun of yourself is a big thing," he added. "I get that professional sport and especially, I mean, he's a cowboy, literally. There's a certain amount of machoism that goes along with that, and that might not translate a lot to dance. I get that. But being able to kind of just release that and almost make fun of yourself and just laugh at yourself, it'll make you enjoy it, which will make you dance better. And I think that's a huge part of it."

With help from Sasha Farber, Simone Biles is sharing an "inspiring" story she's never publicly revealed.

#TeamGoldenGiggles will be performing a Viennese Waltz to "Good Good Father" by Chris Tomlin. "Oh, I've heard a thousand stories of what they think you're like, but I've heard the tender whispers of love in the dead of night," the contemporary Christian artist croons on the track.

When ET caught up with Simone and Sasha during one of their rehearsals last week, they wouldn't tell us the exact story of what the Olympic gold medalist hopes to share, but they did tease that fans should get the tissues ready, as there will be plenty of tears.

"I think this week is very special to Simone because it is the first time she could actually say something she has wanted to say for a long time," Sasha spilled. "It is also a week where Simone does not have to play a character. I feel like after this week, the judges will know why she is the way that she is, and I hope this week we can really open the doors and unravel a lot about Simone. A lot of [the]judges' critiques have been like, 'We want more emotion,' and, 'We want more -- Simone is doing great, [but] she is just doing the steps.' They want to see more conviction, and I think [this dance] will explain why she is hiding the emotion."

"I think she is doing a really, really good job. I think [this story] is something that is really close to her, and I cannot wait for America to actually see it," he continued. "I think everyone's going to cry."

"There's just no right words or anything -- once you can see the story, you will understand it," added Simone, in response to why she hasn't been able to share it before. "I block a lot of things out because I am a gymnast, the emotional side and part of it, but also from my childhood."

"My most memorable year is kind of the lead up to 2016, so that will be fun," she said. "I cannot say too much because it will give it away, but it is like how I was brought up a little bit."

Before our interview ended, Sasha gave us a tad bit more insight, telling ET, "It definitely has something to do with the Olympics," as expected, "because it is such a big, big stepping stone for Simone."

"It is a link in a way," he added. "It will answer a lot of questions that a lot of people do not know about Simone and have wanted to know about her. There is a reason why Simone is the way that she is, and I think this week will really explain it."

Normani Kordei and Val Chmerkovskiy are recalling a bad breakup.

We're also expecting major emotion from #TeamValmani, who will be performing a rumba to "Impossible" by Shontelle.

With heartbreaking lyrics like, "Tell them I was happy, and my heart is broken," and "all my scars are open, tell them what I hoped would be impossible," we have a good feeling the Fifth Harmony starlet will be putting her entire heart and soul into the routine in order to fully bring Val's vision to life.

Rashad Jennings and Emma Slater will be showcasing the meaning of true, unconditional love.

ET exclusively revealed last month that the NFL pro would be dedicating a dance to his father, Albert Jennings, at some point during the season. Now, we're almost positive this is the week we'll get to see that dance, as he has a contemporary routine to Katy Perry's "Unconditionally."

Back in 2005, when Rashad was a starting running back at the University of Pittsburgh, he had to press pause on his dreams and move back home when he learned his dad had to have his leg amputated due to diabetic complications caused from years of drinking and smoking. His father's other leg was amputated a few years later, shortly after he began playing for his second NFL team, the Oakland Raiders, in 2013.

"I want to dedicate a song to my father," he told ET at the time. "Both of his legs had to be amputated, so for me to be able to dance for him, it's just like when I think about playing football. My father doesn't have legs, so I get to run, for him. Obviously he can't dance, so to be able to dance for him I think would be every emotional for me."

"Rashad is a wonderful, incredible person," added Emma. "His story is amazing, about that kind of unconditional love that he has for his dad. He's made his life dedicated to bringing his dad back in a sense … it was just so heartfelt when he told me, so I knew that that was something that [was] going to be in our season."
