(CBS) "Dancing with the Stars" unveiled its first-ever classical week on Monday night, complete with a 46-piece orchestra, violinist David Garett and mezzo-soprano Katherine Jenkins.

The 30-year-old Welsh singer performed two solo songs during the show, and joined another singer for a third.

"DWTS": Kirstie Alley has another dance-floor mishap

Jenkins sang "Con te partiro" during Kendra Wilkinson and Louis Van Amstel's waltz, and "O mio babbino caro" as dance pros Peta and Tristan performed.

She later sang "The Flower Duet" with regular "DWTS" singer Beverley Staunton during Kirstie Alley and Maksim Chmerkovskiy's dance, during which Alley almost lost her shoe (the pair's second dance-floor misstep in as many weeks).
