Britney Spears has a new celebrity superfan - Nicole Richie saw the singer five times on her last tour. The Simple Life star attended the Toxic hitmaker's Circus show in Los Angeles on Friday night.

Spears hasn't performed a full roadshow since The Onyx Hotel Tour in 2004 - which Richie confessed to seeing five times.

She shared pictures from the Circus concert on her blog - and declared it "the best concert I've seen in a while".

Richie writes, "Friday night I went to the Britney Spears concert and had the time of my life. 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."

Richie wasn't the only star to see Spears' L.A. concert - Rihanna, Lindsay Lohan and Jaime Pressly were all spotted in the audience on Friday night.

-Nicole didn't mention whether any of Britney's body parts were "hanging out" though.
