Glad to see someone's all smiles!

On Monday, Melissa Rycroft and the rest of the Dancing With The Stars cast made their way to set to get ready for the night's performance.

Melissa suffered a scare injury during practice on Sunday with partner Tony Dovolani. A rep for the 29-year-old reality star released a statement on her condition Monday afternoon.

"We can confirm Melissa was diagnosed with a disc herniation at the C4-C5 level of her cervical spine," the rep said in a statement. "Melissa's ability to perform [tonight] will be a show time decision."

The dancing gods were clearly in Melissa's favor as not only was she able to perform her routine, but she ended up scoring an astonishing 29.5 out of 30. Way to shake that scare off!

Kirstie Alley and her fellow DWTS alum came together Monday for the premiere of Dancing With the Stars: All-Stars, but instead of going after the coveted mirror ball trophy, the 61-year-old actress has her eyes on another prize!

"I don't give a you-know-what about the mirror ball, I want to just be a size zero like the other girls on the show," Alley revealed in a new video interview with partner Maksim Chmerkovskiy. "Just for five minutes -- I don't even care if the next day I balloon up to a two." The enthusiastic Cheers actress remarkably shed a reported 100 lbs. after competing on the show in 2011, going from a size 14 to 6, so you know she's determined!

Kirstie, along with many former DWTS stars including Pamela Anderson and Chaz Bono, were all gathered for what could be the show's most competitive season yet! Wonder who'll be the first to go?

Two days after J.R. Martinez took home the mirror ball trophy, the Dancing With the Stars champ and professional partner Karina Smirnoff are still celebrating!

The duo, proudly displaying their glitzy trophy, headed to New York for a special appearance on Good Morning America.

Martinez, an Iraq war veteran, discussed the suspenseful DWTS finale. He told the GMA audience:

"I said to Karina … 'Can they just tell us already?' It seemed like the moment was just lasting forever when they were building up the suspense. It's amazing. We've all been putting over three months of work into this. To be able to hold that [mirror ball trophy] up was a tremendous honor."

This is Karina's first win after being a part of DWTS for ten seasons. She definitely deserves it!

Rob Kardashian took second place and talk show host Ricki Lake finished in third.

After last night's performances on Dancing With The Stars, seems as though Rob Kardashian is close to nabbing the coveted mirror ball trophy. Who knew Kim's little brother could move like that?!

Also giving it their all ... fellow finalists Ricki Lake and J.R. Martinez.

Rob and professional partner Cheryl Burke danced the waltz after being coached by judge Bruno Tonioli. After their dance, Bruno told Rob, "You're like the male version of Cinderella who's made it to the ball."

Ricki Lake and her partner Derek Hough performed a sexy cha-cha after being coached by judge Carrie Ann Inaba who called the talk show host "fierce." We agree!

And battling through his foot injury, J.R. Martinez and pro partner Karina Smirnoff danced an incredible cha-cha after getting a few tips from head judge Len Goodman.

After each of their dances, the three duos performed their freestyle. We personally loved Ricki the best! Then again, all three are fantastic dancers.

The winner will be announced tonight!

You'd think a pro basketball player might have all the right moves, but Lakers star Ron Artest (who officially changed his name to Metta World Peace this week), didn't capture the judges hearts on Dancing With the Stars.

Artest and partner Peta Murgatroyd were placed in the bottom three couples during Tuesday night's elimination episode and scored 14 out of 30 points for their cha cha.

Judge Len Goodman said the pair's dance was "all sizzle and no sausage."

Rob Kardashian and Nancy Grace were also in the bottom three but managed to pull out some stunning moves to convince judges to keep them on for another week.

Grace and Kardashian looked on as Artest said his gracious goodbyes: "I want to say thank you to ABC, Dancing With the Stars and Peta. I had a great time!"

Kristin Cavallari and her partner Mark Ballas emerged from Saturday's DWTS rehearsal looking happier and more confident than their competitors. Could it be a sign of good things to come for the pair?

Chaz Bono looked sweaty and tired, but maybe that's a good thing?

Check out Rob Kardashian's look after the jump ... Who's your favorite to win this next season?

Chaz Bono may bring in the ratings for this season's Dancing With the Stars, but will he break out the jazz hands and surprise us all with his dance floor talent?

Cher's son is obviously a bit overweight and could stand to lose a few pounds, so will DWTS help him become the biggest loser???

Dancing With The Stars' Mark Ballas and celebrity partner Kristin Cavallari may be competing against Chaz Bono on the ABC show's upcoming season, but the dancing duo are defending Chaz to the end!

Since it was announced that Bono would compete on the show, critics have sent out vicious backlash because Bono, formerly Chastity Bono, changed his sex.

Our photogs caught up with the competitors as they headed to rehearsal today, where Mark Ballas told us:

"They [critics] should leave him alone! He's a wonderful person."

Chaz's mom, Cher, has also spoken out against critics.
