Britney Spears won't turn 27 years old until Tuesday, December 2, but she already had an early celebration Saturday, November 29 at British nightclub G-A-Y. Her appearance at the club was actually part of her mini tour in support of her highly anticipated LP "Circus", due for release in the U.S. right on her birthday.
Britney, who dropped by the club after performing on Simon Cowell's "X Factor," was surprised by her friends with a birthday cake that was decorated to look like the cover of her album "Circus". They then serenaded her with "Happy Birthday."
Wearing a white top and letting her long blonde hair loosened, Britney was all smile as she blew the candles on the birthday cake. Following the party, she headed back to New York City for a scheduled performance on "Good Morning America" on Tuesday, her actual 27th birthday.
