Lily Allen's had to cancel her American tour and a performance at the MTV Video Music Awards while a row over her right to work over there rumbles on.
The paperwork allowing Lily to work in the US - called a visa - was cancelled after she flew into Los Angeles and was questioned about an assault in London.
Her record company said getting a new visa was taking longer than expected.
Lily said she was really disappointed at having to cancel the tour, which was due to start in San Diego in September.
"I'll be back as soon as I can," she said. "I was really looking forward to playing these shows and being part of the video music awards."
Lily's up for best newcomer - along with fellow Brit Amy Winehouse - at the MTV awards bash next month.
This isn't the first time Lily's cancelled tour dates in America. Earlier this year, she cancelled several shows saying she was "bored" and wanted to concentrate on her second album.
