The singer has reportedly looked into having the heart with a 'K' in the centre removed at a laser clinic, and insiders say the troubled rock star then plans to replace the old tattoo with a demon, contactmusic.com reported.
A source told the Daily Star: "Pete got a female friend to make inquiries at a London laser clinic about having the tattoo removed. After that, he hopes to have a devil tattoo done at his favourite north London tattoo parlour.
"He came up with the idea after penning a song called 'Devil', which went down a storm when he played it to friends. He wants to get it done next week in red ink, complete with horns and everything."
