Jenna Dewan defended her casting on "Dancing With the Stars" Wednesday after fans suggested the "Step Up" star and former Janet Jackson backup dancer might have an unfair advantage in the competition.

I do not know how to ballroom dance,' said Dewan, who specializes in hip-hop and contemporary. 'Let's be clear. It's two different languages.

Past "DWTS" winners have entered with dance backgrounds, but plenty of experienced contestants have fallen short.

The cast of Season 35 of Dancing With The Stars was officially announced on Wednesday, with a fresh lineup of familiar faces trading their famous day jobs for sequins, choreography and a shot at the mirror-ball trophy.

Before breaking out in "Step Up," Dewan worked as a backup dancer for stars including Janet Jackson, Missy Elliott and Christina Aguilera. She has remained connected to dance throughout her career, including hosting "World of Dance" and appearing as a guest judge on "So You Think You Can Dance."

Some longtime Dancing With the Stars fans are less than thrilled about actor Jenna Dewan joining the cast because of her history as a professional dancer, and her pro partner Val Chmerkovskiy is coming to her defense amid all the backlash.

The “DWTS” pro was left off the list of dancers ahead of the new season starring Jenna Dewan, Tatyana Ali, Julia Stiles, and more.

This past May, Dewan appeared on an episode of Live with Kelly and Mark and shared that her daughter Everly, who has previously been into Irish dancing, has been getting into other forms of dance. She added that her daughter is starting to understand why people love her iconic movie Step Up.
