Pete Doherty missed a concert he was scheduled to perform at Ibiza on Monday night. Authorities refused to let the controversial singer fly because he looked drunk in his passport pictures.

Doherty had applied for a temporary passport, but he looked half asleep in the pictures he sent, so it was refused.

"Pete's head was leaning forward. It looked like he was nodding off so the photos were rejected," said a source.

On Saturday, the night before he was supposed to get on a plane, Pete performed a private show in a North London pub, where he was joined in a duet by supermodel girlfriend Kate Moss.

An onlooker told Britain's The Sun newspaper, "Kate sat on the bar wearing a tuxedo, frilly knickers and a hat. She'd get on stage, dance, and then sit down again. It was like a burlesque routine where she would wiggle her bum at the audience."

The couple smoked and drank Guinness and were cheered on throughout the night by the model's friends Sadie Frost, actress Davinia Taylor and Pogues singer Shane McGowan.

Pete and Kate closed the set by kissing in front of the audience before leaving hand-in-hand.

On Friday night, Kate was seen wearing a diamond ring on her engagement finger fuelling rumors the couple are engaged.
