Bad girl gone good? Kelly Osbourne goes under the laser to burn off her rocker tattoos

Kelly Osbourne, who has previously voiced regret over her body-gallery of 15 tattoos, has splashed the cash to begin permanently erasing her "mistakes".

It's hard to envy the former ink-loving rocker the physical pain she's committed herself to as she began the process of having her tattoos burned off with a laser today.

Osbourne posted a video to Twitter of a keyboard tattoo situated on her right forearm gradually fading as the treatment progressed.

Earlier, the 29-year-old had written: "Not looking forward to this afternoon ... I'm getting my first tattoo removal! Its going to burn like the snap of 1000 rubber bands!"

The singer and former wild-child later added: "I did the crime I am now doing the time! #NoPainNoGain! (sic)"

The video, which accompanied the latter tweet, shows the sizeable design ebbing away under the laser's rays as Osbourne, 29, is heard laughing and moaning, "Oh god!"

The person carrying out the procedure then reassures her, saying, "You're doing really good."

Fans of Osbourne - who has undergone an image change in the last three years as she lost weight and began sporting long hairstyles and more conventionally fashionable outfits - responded supportively to her posting, praising her decision.

One of her followers commented: "It's nice to see this change in you Kelly...you really are fine tuning yourself in a fashionable way : ) (sic)"

Back in 2010, the outspoken reality star revealed she was going to get rid of most of her body art when she had the time because she now feels many of the tattoos were a "mistake".

Osbourne even referred to the body art as a form of self-harm, saying at the time: "Some still have a special meaning, like the matching ones my brother Jack and I have of each other's names, but now I feel like some were a mistake."
