Kate Gosselin may be good at juggling her eight kids -- but when it comes to fancy footwork, she's got a lot of work to do.
Gosselin, Pamela Anderson, astronaut Buzz Aldrin and Olympian Evan Lysacek, as well as the rest of the "Dancing With the Stars" cast, made their debut on the hit ABC show Monday night, allowing some performers to show off their ballroom skills -- and others to crumble under the live-TV pressure.
Olympic gold medalist Lysacek and Pussycat Dolls lead singer Nicole Scherzinger topped the judges' scores on the series' premiere, while Gosselin and Aldrin bottomed out in the scores on the first episode of the 10th season of the star-studded show that's featured everyone from Super Bowl winners to supermodels.
Scherzinger earned a 25 for her waltz with professional partner Derek Hough, while Lysacek's waltz with Anna Trebunskaya -- former football star Jerry Rice's ex-partner -- got the Olympic figure skater a 23 out of 30. "The bar has been set," judge Carrie Ann Inaba said of Scherzinger's performance, while judge Bruno Tonioli told Lysacek he danced with the "grace of a swan."
Other top scorers were NFL player Chad Ochocinco and Cheryl Burke, a two-time "Dancing With the Stars" winner, who opened the show, and ESPN broadcaster Erin Andrews, who paired with notorious "DWTS" bad boy Maksim Chmerkovskiy to earn a 21 for their cha-cha.
Pamela Anderson scored 21 points for her rendition of the cha-cha with partner and "DWTS" newbie Damian Whitewood, donning a tight, bright pink minidress for the sexy dance that earned raves from judge Tonioli. "All I can think of is sex, sex, sex," Tognoni said after Anderson danced. "Stripperella is back!"
"The Bachelor" himself, Jake Pavelka, raked in a score of 20 for his performance with pint-sized Chelsie Hightower, opening the dance in a nod to the ABC series by giving Hightower a single rose. Pavelka's new fiancee, "The Bachelor" winner Vienna Giraldi, cheered the pilot on during the performance.
An emotional Shannen Doherty also danced the waltz with former winner Mark Ballas, performing in honor of her father, who she said urged her to be on the show. Doherty, the ex-"90210" star, said before she danced she was so nervous about showing her "imperfections" during the live show she was going to "break out in hives" -- but came back to deliver a solid dance that earned her an 18.
Comedian Niecy Nash, best known for her turn on "Reno 911," surprised critics by tying Doherty's score with partner Louis Van Amstel, dancing a cha-cha that earned her an 18 out of 30 from the judges.
Gosselin was among the bottom of the "Dancing" barrel, earning a 16 out of 30 for a waltz the judges said was "terrible" and showed the TLC reality mom was "nervous" during the performance. "It looked like Tony was pushing a shopping cart around the floor," Tonioli said of Gosselin's dancing.
Moon-walker Buzz Aldrin, 80, also hit bottom in the rankings, earning the lowest score of the night -- a 14 -- for a cha-cha with partner Ashly Costa. Tonioli, again, had a quip for the mishap: "It looked like you still had your moon boots on," he deadpanned.
Rounding out the scores was soap star Aiden Turner, whose uninspired cha-cha with pro partner Edyta Sliwinska netted a 15 out of 30 from the judges.
The "DWTS" results show will air next week, when one performer will be eliminated from the ballroom brigade.
