Pete Doherty has reportedly ended his romance with fiancée Irina Lazareanu.The Babyshambles star - who recently completed a six-week stint in rehab for drug addiction had a blazing row with the Romanian model on Monday night after he grew tired of her constantly following him around. A source told Britain's The Sun newspaper: "Irina has been following him around like a bad smell since the moment she caught his eye. "He got engaged in a moment of madness when he was off his head before he checked into rehab and has been questioning his sanity ever since." She was always telling Pete what to do and where to go, and in the end he had to tell her it was over. Everyone's happy she's gone - it wasn't doing anything for band relations."Pete has now been telling friends he wants to woo ex-lover Kate Moss back.The supermodel ended their relationship in June after Pete allegedly cheated on her with a South African model. Although the 33-year-old beauty is currently romancing The Kills star Jamie Hince, friends say she is still besotted with Pete. In August, it was reported Kate - who has a five-year-old daughter, Lila Grace, from a previous relationship - had rekindled her romance with Pete after the pair spent five nights together at exclusive London hotel Claridge's. During one late-night heart-to heart, Kate told Pete she was "miserable without him and desperately happy with him."
