Kelly Osbourne has slammed Sienna Miller for complaining about the paparazzi's interest in her private life.

Earlier this week Sienna said that she is planning to petition Tony Blair seeking laws that would protect the privacy of celebrities from photographers.

However, Kelly has heavily criticised the actress, blaming Miller's tendency to speak about her private life in public regularly for the interest of over-zealous paparazzi.

According to Contactmusic.com Kelly said: "It's what you get - I mean, don't be famous if you don't want it.

"Don't spill your beans to everyone, and don't be famous if you don't want some attention.

"In some ways, I feel sorry for her, because she has had a lot of trouble, but - come on - you choose to be a celebrity, it's part of the job."
