On this morning's On Air with Ryan Seacrest on KIIS-FM, Heidi demonstrated slightly less vocal range and talent than Bai Ling as she unveiled her new single "Body Language." Then, as though that weren't enough, Spencer -- whose whiteness makes Vanilla Ice look like Jesse Jackson -- flexed his hip-hop talent by rapping.

According to Heidi, "Body" is dance/urban-inspired (she's down like that yo) and she hopes it's played in clubs -- except people won't dance, they'll run for the door! Heidi better hope that the stars are deaf when it comes to this single.
