At the start of the month the 31-year-old star complained of receiving a barrage of faxes warning him that aliens would strike if he appeared on TV in Germany.

Robbie's lawyers immediately branded her as disturbed and took out a restraining order so Conny couldn't go near the singer.

Earlier this year Robbie admitted he believes Britain will soon be invaded by aliens.

He revealed he was convinced the planet was about to be overrun by extra-terrestrials invaders and warned his fans to be prepared for a close encounter of the third kind.

He told Britain's Radio 2: "I've been dreaming every night about UFO's, every night. I can't wait to go to sleep at night because those dreams have been so brilliant.

"I think they are definitely on their way, seriously. Mark my words. From now until 2012 - watch out kids."
