Singer James Blunt is single again after his girlfriend reportedly dumped him. The "You're Beautiful" star had been dating model Natasha Archdale since January, but the brunette is said to have called off the relationship because Blunt has been spending too much time in the recording studio.

A source tells Britain's News of the World, "James and Natasha were such a good couple it just fizzled out. It became very clear that they wanted different things. She wanted long mornings in bed in each other's arms. But he preferred to sit at his piano and write songs."

The star was previously linked to Czech model Petra Nemcova. They split up last year
