Pitbull Serves as Guest Judge on Monday Night’s “Dancing with the Stars”

ABC/Matt Brown(LOS ANGELES) — Mr. Worldwide comes to Dancing with the Stars on Monday night.

Not only will Pitbull perform his hit single, “Fireball,” he’ll also serve as guest judge alongside Julianne Hough, Carrie Ann Inaba and Bruno Tonioli. The nine remaining couples will dance to a mix of his hits and favorite songs.

The Pitbull-themed show comes one week after the stars temporarily switched pro partners. They’re now back with their usual pros, but it may be too late for Michael Waltrip, who was at the bottom of the leader board last week.

The NASCAR driver and owner, who’s reunited with Emma Slater, is worried that he may be eliminated on Monday night. Yet he recently vowed to ABC News Radio, “[W]e’re going to keep working and we’re going to try to get better and better and hopefully people will vote for us because we’re having fun.”

Mean Girls star Jonathan Bennett struggled last week, too. His pro partner, Allison Holker, says they’re in a tough position, but, she adds, “I’m here for the challenge and I’m very excited about it and I’m very confident that Jonathan and I can make a turnaround.”

One former Dancing with the Stars contestant is pulling for the middle-aged competitors. Fifty-two-year-old Karate Kid star Ralph Macchio says he’s rooting for the “not-so-young guys,” because he jokes, “if you’re under 40 you’re cheating!”

Macchio, who finished fourth during the show’s 12th season in 2011, declares, “You got to give some big props — especially right now with Alfonso Ribeiro. Coming out, doing ‘The Carlton’ thing — went viral the next day. …I gotta root for Lea Thompson. She’s in my, that’s my age wheelhouse.”

Dancing with the Stars airs Monday night at 8 p.m. Eastern time.
