Nerves ruled at last night’s season premiere of “Dancing With the Stars” – perhaps the only reality show in which contestants sometimes look like they might need an air sickness bag.

Let’s start at the end of the program, when a couple of the most talked-about celebrities performed their routines.

Reality TV star Kate Gosselin danced the Viennese waltz with professional partner Tony Dovolani, but seemed uncomfortable twirling in her pink dress. (She also appeared frustrated in the rehearsal footage.) “You looked nervous,” said judge Len Goodman.

It’s time again for sequins, boa feathers, fringe and lots of famous faces completely out of their element.

The tenth season of “Dancing With the Stars” begins tonight on ABC with one of the most talked about lineups in the show’s history.

The starting field of 11 celebrities includes reality TV star Kate Gosselin, who will be dancing with Tony Dovalani; actress Pamela Anderson, who is pairing up with Damian Whitewood (a new face on the show) and ESPN host Erin Andrews, who is going for the mirror ball trophy with Maksim Chmerkovskiy.

Every season has a surprise contestant and this time it’s 80-year-old former astronaut Buzz Aldrin, the second man to set foot on the moon. His official “DWTS” bio teases: “He walked on the moon. Now let’s see what those feet can do on Earth.” Aldrin says he’s been practicing hard to be ready for the challenge.

"When I prance out there with the cha cha step, I've got to be filled with far more confidence than I was when we began to land on the moon," Aldrin told CNN before a rehearsal Friday.

Other stars include Olympic skating champion Evan Lysacek, actress Shannen Doherty and soap star Aiden Turner.

Tom Bergeron is back as co-host, but he’s now joined by actress and former “DWTS” champ Brooke Burke who replaces Samantha Harris. (Harris quit the show in January to focus on her correspondent duties at “The Insider,” according to People magazine.)

Also back: Carrie Anne Inaba, Len Goodman and Bruno Tonioli, the three judges on the show.

The first night of competition will feature the cha cha or Viennese waltz.

Who do you think will be the first contestant to go? Who will be the one to beat this season?

Will Donny Osmond pull off an upset tonight on this season’s finale of “Dancing With the Stars?”

It seems possible after an intense evening of competition Monday that ended with the singer receiving his first perfect scores only a week after it looked like he might be kicked off the hit series.

Osmond and his professional dancing partner Kym Johnson and the other two couples left in the show had to dance three routines last night, including two individual numbers and a group “mega mix challenge.”

Kelly Osbourne and her partner Louis Van Amstel first did a kicky, intense Argentine tango. (Those are fun to watch, though whenever I see this tango performed I always feel like the dancers will accidentally kick themselves or each other while doing the flirty leg moves.)

The couple received praise from the judges, though Bruno Tonioli said he wanted more “ripe sensuality.”

Singer Mya and her dancing partner Dmitry Chaplin seemed to solidify their lead after performing a Paso Doble to “We Will Rock You” – a routine that the judges described as flamboyant and amazing and one that received perfect scores.

Osmond and his professional dancing partner Kym Johnson did a nice Cha Cha that earned them three nines. But it was their freestyle dance that had the judges unanimously flashing their “10” paddles. Len Goodman called the Broadway routine an “absolute show stopper,” while Carrie Ann Inaba exclaimed, “Welcome to the hall of fame of the freestyle.”

Mya, on the other hand, disappointed with her “Hairspray” routine, which Inaba called “not outstanding.” Goodman said “it never went anywhere” and Tonioli confessed that he expected something more spectacular.

Osbourne had the crowd on its feet for her freestyle routine set to “I Will Survive,” but the dance seemed to lack some energy and received the lowest score of the three couples.

So, point-wise, Mya is still in the lead, followed by Osmond and Osbourne. But viewer votes could make this a very close one.

Who do you think will win the mirror ball trophy tonight?

“Iron Chef’s” Mark Dacascos and former Dallas Cowboy Michael Irvin didn’t look surprised to be in the bottom three on “Dancing with the Stars” Tuesday night.

Singer Aaron Carter, on the other hand, looked stunned.

Just the day before, he received two perfect scores for an energetic jive that got rave reviews from the judges. Carter, who has been struggling so far in the competition, seemed ecstatic.

Fast-forward to elimination night and the mood was quite different. The singer couldn’t seem to believe that he would either be cut right away or have to fight to stay in the show in a dance off.

Irvin was the first celebrity to be shown the door, which left Carter and Dacascos to battle it out for a spot in the competition.

Dacascos, who was pummeled by the judges on Monday for his samba, performed the cha cha for the dance off, which judge Len Goodman called “top notch.” (Judge Bruno Tonioli expressed his admiration by throwing in a “Hollywood Madam” Heidi Fleiss reference, which left the audience stunned for a moment.)

Carter did another great jive, which tipped the scales in his favor and meant he could stay in the competition - for now.

What did you think of the results?

The competition is getting tougher and so are the judges’ comments on “Dancing With the Stars.”

Last night, the biggest zingers were reserved for Mark Dacascos, host of Food Network's "Iron Chef America," who has had a good run on the show until now.

His samba - performed with new dance partner Anna Trebunskaya, filling in for Lacey Schwimmer who was under the weather this week – seemed like a nice, energetic routine but it really didn’t go over well with the judges.

It was like “Kung Fu Panda doing the samba on the ‘Planet of the Apes,’ ” said judge Bruno Tonioli. (Ouch.)

“It was a mess,” added judge Carrie Ann Inaba.

Maybe it was the jarring black and green costumes the couple wore during the routine?

All of the professional dancers sported outfits designed by their celebrity partners on last night’s show, with mixed results. Louis Van Amstel tried to make the best out of the electric blue, fringe-gone-wild pants picked out for him by Kelly Osbourne.

Fringe worked better for Karina Smirnoff, who wore a great pink dress chosen by singer Aaron Carter. But it was their amazing footwork that earned them a couple of perfect scores for their jive.

“That had enough energy to light up Hollywood,” said judge Len Goodman. (Not to take anything away from Carter's routine, but does it seem like the famously cranky Goodman has been told to be more generous with praise? He's been uncharacteristically complimentary of most couples over the last couple of episodes.)

Two celebrities will be eliminated from the competition tonight. Who do you think should go?

Lots of celebrities have mentioned how they’ve lost weight by competing on “Dancing With the Stars,” and it’s easy to see why.

Last night, many of the stars were barely able to catch their breath after dancing the jitterbug, a bouncy, energetic, athletic – and sometimes acrobatic - dance made popular during World War II.

Donny Osmond and his professional partner Kym Johnson did a fun, train-themed jitterbug that had him huffing and puffing afterwards.

Professional snowboarder Louie Vito seemed so out of breath after his routine that he looked like he was going to do what Osmond’s sister Marie did a few season back on “Dancing:” faint during the judges’ comments.

Judge Carrie Ann Inaba also noted that Vito dropped his professional partner Chelsie Hightower twice during their wild jitterbug. “It was all wacko,” added judge Bruno Tonioli.

Meanwhile, Kelly Osbourne did a fun, cute routine with Louis Van Amstel, but didn’t impress the judges, who called her performance “flat footed.”

“It was like a blueberry muffin without the blueberries,” said judge Len Goodman.

He was more complimentary of some of the couples who danced the waltz on last night’s show, giving the thumbs up to celebrities including Melissa Joan Hart and Michael Irvin.

Tonight, the results show features a double elimination. Who do you think should go?
