Jennifer Aniston celebrated her 40th birthday Saturday night in Los Angeles. The guest list included Aniston's boyfriend, singer and songwriter John Mayer as well as a list of celebrity friends.
Among the stars present were Oprah Winfrey, Tom Hanks and wife Rita Wilson, David Arquette, wife and fellow "Friends" star Courtney Cox, Laura Derm, Sheryl Crow, and Tobey McGuire with wife Jen Meyer, as reported by Access Hollywood.
A source reported to E! Online that Jen and boyfriend John Mayer danced and "huddled close" throughout the night. "She looked hot, and she and John looked really happy."
The birthday bash lasted long into the night and was uninterrupted by the paparazzi as they were kept out of the neighborhood by police. A perfect A-list party with her beau, uninterrupted by paparazzi, gave Jen the best 40th birthday celebration she could ask for.
