Girlfriend Ayda Field dumps Robbie Williams

London (ANI): British pop singer Robbie Williams' long-term girlfriend and American television actress Ayda Field reportedly dumped him over his obsession for aliens. According to a friend, the couple called off their 14-month romance because Williams preferred spending his nights researching on aliens on the Internet.

According to reports, the singer was too preoccupied working on tracks for his upcoming album to spend time with Field, but friends say Robbie hasn''t even stepped foot inside a studio. Instead, it was his nocturnal investigations into the paranormal that finally got Field packing.

"He has become more obsessed than ever recently with aliens. Some nights he would stay up till daylight and not go back to bed," the Sun quoted a source, as saying.

The source added: "I think the break could be permanent - they've been having ups and downs for a while. Robbie is such a generous guy. He gave Ayda everything but he never seemed to take her out for dinner much like most normal guys dating a sexy girl like Ayda would."
