Obsessed might be too strong of a word, but Simple Life star Nicole Richie hasn’t missed an L.A. Britney Spears performance since she was sixteen and admits she is a HUGE fan.

Last Friday night Richie took in Spears‘ Circus Tour when it hit Los Angeles and admits that she attended the pop stars Onyx Hotel Tour five times in 2004.

Richie thinks that Brit’s show over the weekend was the best concert she has seen in a while and had the “time of her life.”  Like most stars these days, Nicole shared her thoughts on her blog.

“I have been a huge fan of Britney 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 but she was too busy tending to her 50,000 fans.”

Other celebrities who took in Britney’s L.A. performance included Rihanna, Lindsay Lohan and Jamie Pressly.
