Sharon Stone: Boy, Oh, Boy-Toy!

The Basic Instinct star steps out with her new beau

Sharon Stone enjoyed a night out with the boys on Friday.

And when we say boys, we mean Stone's 24-year-old boyfriend Chase Dreyfus and a group of his twentysomething pals.

Cougar & Co. were at Eva Longoria Parker and Tom English's Hollywood restaurant, Beso, celebrating what seemed to be Dreyfus' birthday, an onlooker reports.

"Sharon was there with him and his friends from Louisiana," the onlooker says. "She didn't seem to talk to anyone but him."

After dinner, Stone and Dreyfus apparently hopped on a plane for Denver to attend the Democratic National Convention, another source reports.

"Sharon's really taken with him," the source says. They were first spotted getting cozy with each other earlier this month in Las Vegas. They reportedly met while both were doing work on behalf of Planet Hope, Stone and her sister Kelly's charity organization for families in need.

Stone, who has three kids, was married to San Francisco newspaper man Phil Bronstein for six years before splitting up in 2004.

Stone's rep did not comment.
