Nikki Bella joins the celebrity competitors of ABC's "Dancing with the Stars" during the official cast announcement on "Good Morning America."

Nikki Bella is temporarily hanging up her wrestling boots for ballroom dancing shoes as she officially joins the celebrity competitors on Season 25 of “Dancing with the Stars.” The show premieres tonight at 8/7 C on ABC.

John Cena already expressed his support for his fiancee, encouraging the WWE Universe to vote. Don't dial just yet, though. Phone lines open tonight after the show, and stay open for 30 minutes afterward!

Fearless Nikki will waltz into the ballroom with professional partner Artem Chigvintsev, who will also be dancing for his first Mirror Ball Trophy. The official cast announcement was made on "Good Morning America."

While Artem assured "GMA" hosts that he hasn't experienced a Bella Buster yet, Nikki hasn't ruled it out.

"I try to fight him every rehearsal," Nikki joked.

Brie Bella and mom Kathy revealed on The Bella Twins YouTube Channel that they're already in Hollywood, getting ready for tonight's big premiere.

The Season 25 celebrity cast also includes former NFL star Terrell Owens, Barbara Corcoran of “Shark Tank,” actor Frankie Muniz, and married entertainment personalities Nick and Vanessa Lachey.

The Bella Twin is the third WWE Superstar to cha-cha into the “Dancing with the Stars” ballroom. Chris Jericho competed in Season 12 in 2011 and was eliminated fifth out of 11 contestants. Stacy Keibler competed in Season 2 in 2006 and placed third.
