James Blunt angers supermodel girlfriend

Petra Nemcova is worried about the future of her relationship with James Blunt.

The supermodel was furious when the You're Beautiful singer told her that he couldn't attend a party she was hosting during London Fashion Week at the last minute. She is now concerned that their romance will hit the rocks if Blunt doesn't make more of an effort to spend time with her.

A friend told the Sunday Mirror: "Petra has been really upset because James told her that he would definitely be there. But then he changed his mind and told her he had an important recording to do in Ibiza.

"Petra now feels that he is putting his career before her party - proceeds were going to her charity, the Happy Hearts foundation, which helps victims of the tsunami.

"It means so much to her. She understands that James is one of the biggest pop stars in the world - but she really wants him to spend more time with her. She's worried they won't last if they don't see more of each other."
