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."
It is also alleged that the couple had a blazing row last week after Kate
saw the Babyshambles singer flirting with a French woman at popular London
concert venue, Brixton Academy.
The source is quoted by Britain's Daily Star newspaper as saying: "They were
screaming at each other the whole night.
"Kate knows he loves her but he's a free spirit and there's no holding him
down. He hates it when she gets jealous. She gets really wound up by him
getting into intellectual conversations with arty young women who idolise
him as a poet."
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.
