EXCLUSIVE: Peta Murgatroyd and Nick Viall Get Candid About Double Dating and the 'Great Energy' on 'DWTS'

By
Nick Viall is still feeling the energy following his ballroom debut on Dancing With the Stars!
The Bachelor star wowed the crowd during the season 24 premiere of the dance competition show on Monday, dancing the Cha Cha with his pro partner, Peta Murgatroyd. ET caught up with the pair just moments after the show wrapped, where they opened up about their first dance, and what it's like to double date outside of rehearsals.
"There's so much energy," Nick, 36, explained to ET's Cameron Mathison, saying this experience is "very different" from anything he's ever done before. "I just tried to be in the moment. The great energy was amazing, it was so much fun, but I don't quite remember all of it."
"It was pretty cool," he continued, "and I have this one [Peta] by my side, so I'm pretty lucky."
Peta chimed in, telling ET that they've been spending a lot of time with each other, even when the cameras aren't rolling. #TeamBabyGotBach has enjoyed a few double dates already, with their significant others -- Nick's fiancée, Vanessa Grimaldi, and Peta's fiancé, Maksim Chmerkovskiy.
"It's really fun and I just wanted to get to know Vanessa," Peta, 30, dished. "She is going to be with us every step of the way, so it's just awesome to have dinner and chill."
"I think you got to have a good balance between fun and work, and I think we nail that," she added. "I think we're goofy, but we know when to work hard and when to knuckle down, get all the steps down so, yeah, I think that's really our thing."

That's when Maks, who is partnered with former Glee star Heather Morris this season, crashed our interview, joking about being their biggest competition this season. See the cute moment in the player above!
New mom Peta also admitted that she and Maks were missing their son, Shai. The two welcomed their first child together two months ago, and haven't been able to stop gushing over him ever since. Maks previously joked to ET that he and his brother, Val, were going to "use" him for votes!
"It's really hard," Peta confessed to ET on Tuesday. "It's hard. We miss him so much. I mean, it's like part of your heart [is] left at home."
"It's very surreal actually," she continued, "but I just can't wait to get home to him tonight."
ET also caught up with #TeamDenimNDiamonds on the carpet -- Sharna Burgess and Bonner Bolton -- where they explained that "unintentional" onstage moment that went viral when Nick and Peta were receiving their scores from the judges.
