Jennifer Aniston threw herself a star-studded 40th birthday party at her new Beverly Hills home February 7 night.

The former "Friends" actress, who reaches the landmark age on February 11, and her boyfriend John Mayer danced and huddled close all night at the party. "She looked hot and she and John looked really happy," E! News cited a source ay saying.

The guests include Oprah Winfrey, Sheryl Crow, David Arquette and wife Courtney Cox Arquette, Tobey Maguire and wife Jen Meyer, Laura Dern, Kevin Nealon, and Tom Hanks and Rita Wilson.

The star-studded party was held inside and outside of her sprawling hillside home.

We're told that the party began shortly after 7 p.m. and revelers partied well into the morning past 2 a.m.

Another bonus for Jen for the night: she kept the media at bay. "The police kicked all the paparazzi out of the neighborhood," says a source.

Jen recently told France's Closer magazine, "Everyone's been asking me if I worry about being nearly 40, but no, not really. These days I'm a lot more serene and I'm ready to embrace a new decade."
