Britney Spears actually wears underwear for birthday night-out

After her antics over the last week, it does actually feel like news to say that Britney Spears wore underwear for her birthday night out over the weekend.

Britney turned 25 on Saturday and spent the day with eldest son Sean at the Los Angeles zoo. An onlooker revealed: “She was doing monkey impersonations. Sean thought it was hilarious.”

Meanwhile, new best friend Paris Hilton was spotted buying the birthday girl some presents - necklaces, a dress and shirt, and a “Birthday Girl” tiara at celebrity-favourite boutique Kitson.

The two met up later, with Britney wearing a retro patterned mini-dress - and those knickers - for a meal and cake at Mr Chow’s in Hollywood before heading over to Hyde for a grown-up style party with Paris and Nicky Hilton, as well as other celebrities such as Chris Rock and Fergie.
