Let's get ready to rumba.
The Season 19 cast for "Dancing With the Stars" was announced Thursday morning on ABC's "Good Morning America," and, as usual, it features a kooky assortment of celebrities, including a soap star, a YouTube sensation, auto racer, fashion designer and an Olympian.
The 13 new hoofers, along with their pro partners, are as follows:
-- Jonathan Bennett, "Mean Girls" star (with Allison Holker)
-- Randy Couture, mixed martial arts champion (with Karina Smirnoff)
-- Tommy Chong, of Cheech and Chong (with Peta Murgatroyd)
-- Betsey Johnson, fashion designer (with Tony Dovolani)
-- Lolo Jones, Olympic bobsledder (with Keo Motsepe)
-- Bethany Mota, YouTube teen lifestyle maven (with Derek Hough)
-- Janel Parrish, "Pretty Little Liars" star (with Val Chmerkoskiy)
-- Alfonso Riberio, star of "French Prince of Bel-Air" (with Witney Carson)
-- Sadie Robertson, "Duck Dynasty" diva (with Mark Ballas)
-- Anthony Sabato Jr., "General Hospital" star (with Cheryl Burke)
-- Tavis Smiley, PBS talk show host (with Sharna Burgess)
-- Lea Thompson, film and TV star (with Artem Chigvintsev)
-- Michael Waltrip, NASCAR champion (with Emma Slater)
The new cast features a wide range of ages with Robertson, 17, and Mota, 18 on the young side, and Johnson, 73, and Chong, 76, representing the AARP crowd.
Among the changes this season: Maks Chmerkovskiy, the bad-boy pro of the ballroom is sitting this one out. Meanwhile, Julianne Hough will be a fourth judge, along with Carrie Ann Inaba, Len Goodman and Bruno Tonioli. Also, Motsepe is the show's first black pro dancer.
Tom Bergeron and Erin Andrews return as hosts. Season 19 of "Dancing With the Stars" premieres Sept. 15 (8 p.m.) on ABC.
