Vanessa Hudgens shows her booty poppin’ moves on Leno.

Vanessa Hudgens talks like a Valley Girl, but she’s got a booty straight out of Compton. She gave Jay Leno an eye-popping exhibition of her booty poppin’ abilities after Jay brought up Madonna and the Material Girl’s blow out parties.

“One thing I remember about Madonna parties is the music is so loud,” said Jay, before Vanessa cut him off.

“Oh my gosh!” she giggled. “I felt like a grandma.”

She recounted being at a party with Selena and they started dancing. But Vanessa said the music was so loud she had to step outside because her ears where ringing.

“Did you have a dance contest?” Leno asked. Vanessa put up her hand to stop him. “It was amazing,” she said.

“One of my most prideful moments, I think. I had a dance off. It’s Madonna’s party so she’s there, and she has her dancers there. They’re dancing getting the party spiced up.

They were all dancing with each other. There were dance offs happening, so I was like, ‘I’ve got to jump in on this action. They need some Vanessa in this,;” she said.

And, she took the prize! “When it comes to my dancing… I hate to admit it, but there’s a lot of booty poppin'”

Jay, of course, immediately asked for a demonstration. And, he got one.
