EXCLUSIVE: Britney Spears’ Birthday is G-A-Y OK!

As everyone in the world knows (even Diane Sawyer!), Britney Spears turned 27 years old on Tuesday. Pop music’s reigning comeback queen got a jump on the celebration over the weekend with a big birthday bash at G-A-Y nightclub in London.

The jam-packed celebration was right in keeping with the Circus theme of Spears’ new album. Drag queens, revelers and choreographer Andres Fuentes (the man responsible for Spears’ wicked new dance moves) were all under the G-A-Y big top.

And because Britney Spears is a sharing person, now you can feel like you were there with these EXCLUSIVE photos, direct from the birthday girl’s private picture stash.

Check ‘em out and bask in the revelry! If it helps you fully get into the spirit of things, feel free to cross-dress before clicking through the gallery.

It would also be a nice gesture to head over to Britney’s official Web site and leave your birthday well-wishes.
