British pop star Lily Allen has reportedly cancelled her U.S. tour to return to London because she is homesick. Allen pulled out of a gig in New York last Thursday without any official reason, and now her American tour dates next month - which aren't even listed on her official website - have been thrown into doubt.

Allen was due to begin her tour in Seattle on May 24, but the owners of the Minneapolis venue where she is due to play say the date is off, fuelling suspicions she is to come home earlier than expected.

Earlier this month Allen complained of missing her home comforts, writing on her MySpace page, "Is it really important to break America? I'm bored."

She's scheduled to next appear at the Coachella Festival in California on April 29, but it's unclear if this will go ahead.
