Richie: 'I'm a massive Britney fan'

Nicole Richie has revealed that she is a "huge" Britney fan.

The 27-year-old admitted that she saw the 'Toxic' singer five times on her last tour and was thrilled to be able to watch her live again in Los Angeles last weekend.

"Friday night I went to the Britney Spears concert and had the time of my life!" she wrote on her blog.

"I have been a huge Britney fan since I was 16 and have been to all of her concerts. I think I went to five shows of her last tour."

"I have been looking forward to seeing her back on stage for years, and it was amazing! It was really hard to get pictures because she never stood still. I yelled and asked her to, but she was too busy tending to her 50,000 other fans."

Other celebrities spotted at recent Britney live shows include Rihanna, Lindsay Lohan, Victoria Beckham and Avril Lavigne.

Spears begins her mini-residency at London's O2 arena on June 3 and plays a one-off show in Manchester on June 17.
