Dancing With the Stars season 20 kicked off its 10-year anniversary celebration in its glittered ballroom with an introduction of the new season's cast by returning hosts Tom Bergeron and Erin Andrews.

Carrie Ann Inaba, Len Goodman, Bruno Tonioli and former pro dancer Julianne Hough each resumed their season 19 seats at the judges' table. Season 19's Sadie Robertson also attended the premiere, not sitting far from a new, 14-karat-gold-plated mirrorball trophy revealed at the start of the show.

Since it's week one, here's a breakdown of the new contestants.

Fourteen-year-old Hunger Games actress Willow Shields and pro partner Mark Ballas danced a cha-cha to start the night. "It was like a glass of Alka-Seltzer: sparkling and bubbly," said Goodman. The show's youngest competitor earned 25/40.

Business tycoon and Shark Tank star Robert Herjavec — who, during his introduction to partner Kym Johnson, offered her his Ferrari were they to win — filled the second dance slot with a cha-cha. "You have really sharp legs," said Hough. The judges gave the pair 28/40 for their dance.

R5 bass player Riker Lynch and pro partner Allison Holker did not utilize the ballroom floor but performed a jive onstage to a circle of fans. "I can't wait to see you do the next dance next week," said Tonioli. A second cousin to the Houghs, the blond-haired musician earned 31/40.

Recognized for wearing a bikini while eating a cheeseburger in her 2015 Carl's Jr. Super Bowl commercial, model Charlotte McKinney and partner Keo Motsepe — who taped her breasts down during practice — danced a jive, which earned 22/40.

Grammy winner Patti LaBelle said, "I'm here to show America that Miss Patti can dance." Bedazzled in a gold gown, LaBelle and Artem Chigvintsev danced a Foxtrot that Goodman said had "a lovely naturalness about it." They earned 25/40.

The Bachelor's Chris Soules, who is engaged to his own blond Whitney, who was present in the audience, performed a country-esque jive with partner Witney Carson. Despite Hough saying, "your feet were a little loose," the pair earned 26/40.

NFL free agent Michael Sam and Peta Murgatroyd got their "Uptown Funk" on for a cha-cha that earned them a 26/40. Tonioli said it "was hot," but Goodman said Sam's feet were "atrocious."

Five-time Olympic medalist Nastia Liukin and five-time mirrorball trophy winner Derek Hough gave the audience a Foxtrot performance that scored 30/40. "It was sweet and delicious," said Goodman.

LMFAO singer RedFoo and Emma Slater brought a colorful "Juicy Wiggle" cha-cha. "You dance like your hair: a little wild and unkempt," Goodman said before the two earned 22/40 for the premiere, but RedFoo replied: "I'm just so dedicated to learn the technique."

Double amputee Noah Galloway and Sharna Burgess danced an inspiring cha-cha. The pair earned a 26/40 for their emotional performance, and Burgess was praised for her creative choreography.

Three's Company actress Suzanne Somers and partner Tony Dovolani channeled her Thighmaster infomercial for a 25/40-scoring cha-cha. Somers told the audience that she came onto the show to prove that "blondes have more fun."

Singer-actress Rumer Willis and Valentin Chmerkovskiy saved the highest score for last. The pair danced a chandelier-lighted Foxtrot and earned 32/40. "This could be your season," Goodman told Val. Willis' parents, Bruce Willis and Demi Moore, cheered from the audience.

RedFoo and McKinney were at the bottom of the scoreboard and are in jeopardy of being sent home next week, while Willis and Lynch's scores are sure to secure them past week two.

Tune in to ABC at 8 p.m. on March 23 to see which couple will be sent home.
