The singer - son of late Beatle John Lennon - was shooting a video for new track, 'Dead Meat', at the Spanish Mission, in California, when a fan followed him into the bathroom.

Sean - who convinced rumoured girlfriend Lindsay Lohan to star in the promo - refused to sign his name for the besotted admirer while he relieved himself, but did agree to give out his autograph once he got outside.

Notorious party-girl and ex-girlfriend to Sean Lennon, Bijou Phillips, is reportedly spitting fire over rumors that Sean is now dating Lindsay Lohan.

One question, who ISN'T Lindsay Lohan dating? Anyway, Bijou dated John Lennon's son Sean for four years, which is an eternity among the Hollywood set, and she was overheard at the L.A. club Teddy's screaming, "Lindsay Lohan dating Sean? How could he?! How could he stand to be with her?"

John Lennon's widow, Yoko Ono, attempted to stop the filming of the movie starring Lindsay Lohen about his murder. "Chapter 27" was being filmed at the Dakota building in New York, and Yoko immediately checked if the Dakota building had the right to refuse their filming.

Rumor has it that notorious party girl Lindsay Lohan is now dating John Lennon's son, Sean. The two met when Lindsay was researching for her new movie, "Chapter 27," which chronicles the murder of Sean's father John Lennon.

Sean, 30 told reporters that he was looking for a lover and even gave qualifications. "She must have a high IQ, aged between 18-45," he reportedly said. "She must have no psychological disorders or deformities."

The Beatles hired prostitutes when they couldn't get sex from groupies, John Lennon once confessed.

In a long lost interview, the late musician told journalist Jann Wenner in 1970, just months after the legendary band split: "If you couldn't get groupies, we had whores. Whatever was going.

John Lennon's killer allegedly considered himself a "white knight" on a crusade.

Tapes set to be played on US television this week show Mark Chapman - who shot the legendary Beatle in 1980 - hoped to make his mark by murdering the star.
