Drew Barrymore is anxious to shake what her Momma gave her on stage with the Pussycat Dolls-if only for one performance. After watching the Dolls live performance at Caesar’s Palace Las Vegas on January 16th, Drew is “itching to get up on stage and show off her moves!”

“Drew is a flower in her hair girl, but she also loves to get sexy,” a spywitness reveals to Star Magazine. “She was talking about it all night with Justin (Long). Justin, being the supportive boyfriend, was ‘egging her on, like ‘Do it, baby, do!’ He obviously really into her and wants to see her show off her naughty side.”
