'Dancing With the Stars': Chynna Phillips & Tony Dovolani Are Excited For Cher

It's no secret that Chaz Bono has been having a rough couple of weeks on "Dancing With the Stars." After stunning the crowd in week one with his feisty cha cha, Bono injured his knee in dance rehearsals and hasn't been able to regain his momentum. In fact, Bono has come in at the bottom of the leaderboard for the past two weeks.

But that might all change after tonight because Cher is finally heading to the ballroom to support her son on "Dancing With the F-cking Stars." It's the moment everyone -- the fans, the judges and even the celebrities -- has been waiting for.

And she won't be alone. Chaz's stepmother, Mary Bono Mack, will also be in attendance at Monday's (Oct. 10) week four performance to see Chaz take on the tricky paso doble with partner Lacey Schwimmer.

However, there's one "Dancing With the Stars" contestant that's going to try and win Cher over with her stylish, sultry tango.

"I'm a huge fan," says Chynna Phillips. "I'm actually really excited for her to come because I'm doing a very stealth, sexy tango. it's very dramatic, very Cher, and I'll think she'll love it."

As for her partner -- and choreographer -- Tony Dovolani, he couldn't agree more. After all, he's been waiting for Cher's arrival for quite some time.

"I'm so excited," says Dovolani. "I asked Chaz from the very beginning, hey, when is your mom going to come? He goes, well, I'm hoping she comes, and now that she is going to be there, I'm just so happy for Chaz that his mom is going to come and support him. And I can't lie, I can't wait to meet her [laughs]. She's a legend. And not only that, but parent support is always needed, no matter who you are or what you do. It just comes second to none."

Will Cher have the power to keep Chaz dancing for one more week? Tune into the week four show Mon., Oct. 10 at 8PM ET on ABC to find out.
