Check out this sneak peek of Tuesday’s (June 3) episode of “America’s Got Talent,” available exclusively here at Zap2it.

In the video, we meet Sean and Luke, two guys who take the stage looking like they’re about to drop some beats — but they aren’t rapping, they’re tap-dancing!

“I really enjoyed it, especially your facial expressions,” says Heidi Klum, who gets called out by Howard Stern for flirting with the boys. But one of them is 18, so that’s OK, because as Howard points out, he’s almost the same age as Heidi’s boyfriend. Hee!

“America’s Got Talent” airs Tuesdays at 8 p.m. ET/PT on NBC.
