Can’t touch this!

They’re cute as buttons, and they know what they’re doing. They’re Miami dance crew The Untouchables (ages 8-13), who got raves from America’s Got Talent judges Sharon Osbourne, Howie Mandel, and Howard Stern at the Tampa auditions (when the kids jumped around to the Pitbull- J.Lo On the Floor collab), then made it through another recent round in Las Vegas.

Osbourne called their peppy act “precise,” and told them they were at a high level technically.

Mandel said they were “phenomenal,’’ and even cranky Stern thought the kids were “totally captivating.’’ Though the shock jock added, “Puberty is your enemy,’’ in a nod to Shirley Temple.

The group hails from the same studio, Dance Town in Doral, as last year’s top 10 AGT act, The Miami All Stars, with some siblings between both groups. Now it’s up to viewers to vote for these whippersnappers; the quarterfinals will continue when the show returns Tuesday at 8 p.m. If they win the NBC competition, $1 million (shared) goes in their little pockets.

Easy riders

He’s got those cute, innocent eyes, and charming smile. But who knew John Corbett was so shy? The former Sex and the City star (sensitive Aidan who got crushed by Carrie) and current Applebee’s pitchman is coming to town for a charity event but was reluctant to chat. The West Virginia native, 51, wanted to know the topics before speaking with a Miami Herald reporter. Perhaps he’d prefer to keep his relationship with Bo Derek sacred. Or maybe he wanted to keep details of the My Big Fat Greek Wedding 10-year anniversary DVD under wraps (it’s out in September).

See if you can get anything out of him at the third annual Kiehl’s LifeRide for amfAR, a nine-day charity motorcycle ride for HIV National Awareness Month that kicks off at the beauty brand’s Lincoln Road store from 11 a.m. to 1 p.m. Friday. Other riders are model Tyson Beckford and My Name is Earl star Jason Lee (congratulate him: wife Ceran just gave birth to their second child, a son named Sonny).

There will be a pop-up picnic prepared by Hell’s Kitchen contestant, food-truck maven Robyn Almodovar, as well as a photo booth, temporary tattoo parlor, music, and 15 percent discounts on Kiehl’s purchases. This is the first time Miami Beach has been included in Kiehl’s LifeRide for amfAR; Kiehl’s will make donations at each of the eight stops — totaling $90,000.
