Britney Spears celebrated her 25th birthday this weekend by clubbing in Hollywood with Paris Hilton and Black Eyed Peas star Fergie.
Before partying at Hollywood hotspot Hyde, the pop tart celebrated with friends at Beverly Hills restaurant Mr. Chow.
Arriving in a skin-tight mini dress, Britney joked about her recent knickerless shots by bending over and flashing her lingerie at the paparazzi.
Earlier in the day, Spears celebrated her big day with her sons Jayden James and Sean Preston by taking them on a trip to the LA Zoo.
