'The Bachelorette': The 15 Most Dramatic Moments, From Kaitlyn's Bedroom Confession to DeMario's Girlfriend

We love this show!!

Hannah Brown is our 15th Bachelorette!

The Bachelor spinoff will celebrate its 15th season when Brown kicks off her journey to find love on May 13 -- and while Hannah's season is sure to be dramatic, let's not forget the years and years of juicy moments we've gotten from Bachelorettes past. 

Years after Kaitlyn Bristowe's season ended in 2015, we're still thinking about her and Nick Viall sleeping together before fantasy suites -- and his calling out of Andi Dorfman on her After the Final Rose the year before. Between the Viall files, dramatic breakups and those special contestants who went on the show with girlfriends back home -- looking at you, DeMario Jackson! 

In no particular order, here are the 15 most dramatic moments in Bachelorette history. 

Season 11: Double Trouble Premiere Ends in Tears

While the franchise had started the season with a double Bachelor before, season 11 marked the first time they started the season with two Bachelorettes: Kaitlyn and Britt Nilsson. It was up to the men to decide which woman they wanted as their Bachelorette, and they chose Kaitlyn, forcing Britt to leave in tears. 

Season 11: Multiple Meltdowns

The season went on with Kaitlyn -- though not all of the men were on their best behavior. Contestant Ryan slapped Kaitlyn's butt on night one, while Ian later called her shallow and surface level. And then former besties -- dubbed the "Brokeback Bachelors" JJ and Clint turned on each other and fought, leading to a full-on JJ breakdown. 

Season 12: Chase-ing His Composure

JoJo Fletcher's season featured several dramatic breakups, including one with Chase McNary -- who had just told JoJo that he was in love with her. He had never declared his love for a woman before. "You 100 percent made me regret saying that. So now love equals 'Get the f**k out?'" he asked before storming out. 

Season 12: Left on the Tarmac

The week before, JoJo shockingly broke up with frontrunner Luke Pell after hometown dates. The dramatic split led her to breakdown on the tarmac after a tense rose ceremony in an airplane hangar. 

Season 6: Someone Back Home

Ali Fedotowsky's journey to find love hit a real rough patch towards the end, when Frank eliminated himself at final three, revealing he was still in love with his ex-girlfriend back home.

Season 13: DeMario...

DeMario's girlfriend actually came back to find him on Rachel Lindsay's season of The Bachelorette -- providing for some very meme-able moments. Who's this? 

"Let me tell you something. I'm not here to be played, I'm not here to be made a joke of, which is what I feel like you're doing right now with me. So, I'm really going to need you to get the f**k out!" Rachel told DeMario. Bravo! 

Season 10: TMI

It was contestant versus lead again on Andi's After the Final Rose, when her runner-up, Nick, showed up clearly still bitter. "If you weren't in love with me, I'm just not sure why you made love to me," he said. Too much! 

Season 6: Rated R Runaway

We had another badass moment when Ali chased down Justin "Rated R" Rego through a hotel after she found out that he had a girlfriend back home. To top it all off, he was walking with a boot after breaking his leg -- quite the escape!

Season 12: Fights on Fights on Fights

Before hurling the "F" word at host with the most Chris Harrison on Bachelor in Paradise, "Bad" Chad Johnson earned his nickname as the clear villain of JoJo's season. He first fought with Evan Bass, ripping his shirt, before threatening to de-limb the cast, arguing with Jordan Rodgers and storming off into the woods on his two-on-one date. A true Bachelorette moment!

Season 8: Get the F Out

Emily Maynard pulled a Rachel when she told entitled contestant Kalon to GTFO after he called her daughter "baggage" in season eight. And she didn't bother accepting his insincere apology after filming wrapped. "I hope you find faith in something bigger than your Prada shoes and your rented helicopter," Emily hissed at him on Men Tell All. Preach!

Season 9: It Was Supposed to Be You

Frontrunner Brooks devastatingly broke up with Desiree Hartsock on season nine, with fans -- and Des -- thinking he was her final pick. As she revealed during their breakup, she was going to tell him she was in love with him that day, but alas, not everything goes according to plan in Antigua.

Season 13: Crying Her Eyelashes Off

Rachel's breakup with Peter Kraus was just as devastating -- so much so that our Bachelorette cried off her fake eyelashes. The pair's goodbye seemed to last an eternity, and it was clear they had real feelings for each other; Peter just couldn't commit to an engagement. 

Season 5: Finally Listening to the Warnings

There's always a "bad guy" on The Bachelorette, and Jillian Harris didn't send hers home until final four, realizing that Wes, who had a girlfriend back home, wasn't on the show to find love.

"The first guy ever on The Bachelorette to make it to the top four with a girlfriend," Wes congratulated himself in the limo ride home after his elimination in Spain. "My acting days are over. I've definitely gone as far as I could possibly have gone with Jillian."

Season 7: Uncalled For Insults

Bentley had two sides on Ashley Hebert's season of The Bachelorette -- and one of them was just nasty. While sweet to her face, Bentley told the cameras that he had no interest in the lead, was looking forward to making her cry, and "would rather be swimming in pee than planning a wedding with her." Jeez, OK!

Season 11: The Nick Situation

After making a splash on Andi's Bachelorette season, Nick came back to the show for a chance with Kaitlyn. The pair immediately clicked, having spoken before her season kicked off, and she ended up sleeping with him before fantasy suites. Kaitlyn ended up telling the rest of the cast that she and Nick had gotten intimate, leading to major beef between him and another frontrunner, Shawn Booth -- who later won Kaitlyn's final rose after she brutally rejected Nick in the finale. 

The Bachelorette returns Monday, May 13, with a special reunion episode on May 6 at 8 p.m. ET/PT on ABC. Join ET's Bachelor Nation Facebook group here
