Bristol Palin opened up Friday night during an appearance on 'The Tonight Show with Jay Leno,' according to, in order to address her rumored diva-like demeanor in rehearsals (with ballroom pro Mark Ballas) for her new gig on ABC's 'Dancing with the Stars.' And the young single mom also took the opportunity to aim a few wisecracks at her ex, Levi Johnston.

So, has she been a demanding diva in the dance studio, even just a little bit? "Literally, I was thinking about it today: the only thing I've ever asked for is a velcro mic pack, so I don't have to wear it on my belt loop," said the 19-year-old 'DWTS' newbie. "That's the only thing I've ever asked for."

Turning to the topic of her ex, she was candid. "He's changed. Night and day, definitely," she insisted. "The guy I fell in love with was a hard-working Alaskan man that didn't want to wear straight-legged jeans and get chased by Radar."
