Jenna Johnson Dishes on ‘Say Yes to the Dress’, Her Vegas Bachelorette Party & More 'I Do' Details (Exclusive)

The ‘Dancing with the Stars’ pro and fiancé Val Chmerkovskiy share all the details as they prepare for their upcoming wedding.

From selecting her magical dream dress to a surprise bachelorette party in Las Vegas, Dancing with the Stars pro Jenna Johnson is living every bride’s fantasy as she counts down to becoming Mrs. Chmerkovskiy.

“It is every girl’s magical warehouse of wedding dresses,”Jenna gushed of her experience at Kleinfeld Bridal in NYC. The 24-year-old dancer said her search to find the perfect dress for her upcoming wedding to fellow DWTS pro Val Chmerkovskiy will be featured on an upcoming episode of the hit TLC reality series Say Yes to the Dress.

“I watched it growing up all the time, so to be able to go there and pick out my dress and meet Randy, Lisa and the whole crew was a dream,” she continued, when ET caught up with her and Chmerkovskiy while they tasted wedding cakes at Vanilla Bake Shop in Santa Monica.

Fans got a glimpse of Jenna’s upcoming episode when the 24-year-old dancer shared her trip to Kleinfeld Bridal on social media in January. "I said YES to the Dress!!!!!!!" the bride-to-be captioned a smiling pic, showing her standing on a circular platform wearing a white mini-dress with heels and a black blazer.

“I went in and I knew what I wanted,” Jenna told ET’s guest correspondent, Telemundo’s Francisco Cáceres. “It was the first one and I was like ‘I know this is it.’ I tried on MANY, but I just knew.”

“I tried on a lot of dresses [before going to Kleinfeld’s] and I know what looks good on me and what doesn’t, so I’m pretty particular too,” she added.

But the one thing fans haven’t caught a glimpse of yet is which dress she said “yes” to! Jenna’s future sister-in-law, Peta Murgatroyd, who was on hand for the big moment, teased that Jenna looked like a “goddess” in the gown she selected.

"It was actually amazing, like, I've never been into that place before... I was astounded when I walked in," Peta recently told ET’s Katie Krause of the crew’s experience at Kleinfeld’s. "I think I could tell by her face and what she was saying that that was it and, like, when you know, you know."

“I can’t wait to see her,” Val said, admitting that he also doesn’t know what gown his future wife selected, joking that the dress will be a “marshmallow of beauty”. But how does Val imagine his bride will look as she walks down the aisle? One word — “Gorgeous.”

Jenna also shared that she had a pretty “epic” bachelorette party, when the ladies from the DWTS Winter tour and fellow DWTS pro Lindsay Arnold (who flew in for the festivities) surprised the bride with a trip to Absinthe in Las Vegas for the big night. The group also decorated one of the tour buses for a girl-only party – No Val’s Allowed.

“It was epic and everything I hoped my bachelorette party would be. And to have it in Vegas with all of them, it was so much fun,” Jenna said about getting a night off from dancing and wedding planning. When asking how raunchy the party got or if it stayed pretty PG-13, Jenna laughed, saying “No, I think I would’ve been traumatized.”

For Val’s bachelor party, his friends took him to Tulum for a getaway that also coincided with his birthday.

“All my friends are fathers and husbands and they were so excited,” he explained. “Like the thing about me is I want something laid back. I’m not trying to turn up and they were a little upset about that.”

Val also gushed about his friends celebrating this special time in his life with the “sentimental” trip, since he is the “last wolf” to settle down. And though the party may not have gotten too wild, he admitted that were was quite a bit of mescal consumed during the vacation.

Speaking of wild, Val expects the wedding reception to be a pretty impressive dance party, especially since Sasha Farber and Emma Slater helped them find their wedding band — Eli’s Band — a group who can handle all of the pop, Latin & Russian music they’ve requested for the playlist, plus their first dance tune “La Vie en Rose”.

“There’s gonna be a lot of dancing,” he predicts. “And I’m excited for that because obviously we have a crowd of friends and our guests are some of the best dancers in the world. But again the magic is in that spontaneity!”
