The 32-year-old supermodel is calling the rules 'Kate's Commandments' and insists the junkie rocker must stop taking drugs, end contact with his 'loser' friends and call her at least thee times a day.

Pete, 27, must also stop flirting with his groupies if he wants to make Kate his bride, start eating properly and spend two hours every day writing poetry and music.

A source said: "Pete is prone to going AWOL. Kate has warned Pete that if he doesn't comply, their relationship is off."

Kate and Pete are apparently planning to marry in Ibiza on her 33rd birthday in January next year.

She agreed to marry the rocker after he checked into The Priory rehab centre to battle his addictions to crack cocaine and heroin. Since leaving rehab Pete has managed to stay clean.
