The man who killed late Beatle John Lennon has reportedly become obsessed with actress Lindsay Lohan - turning his cell into a shrine to the star. Mark David Chapman, who has already served 27 years in jail for assassinating Lennon in 1980, has allegedly begged the Mean Girls star to visit him at Attica State Prison, New York.

The murderer has pictures of the troubled star, who plays his girlfriend Jude in the movie Chapter 27, plastered all over his walls at the prison, according to Ireland's Sunday World newspaper. A source at the prison tells the publication, "He has been pleading with the authorities to let him write to her and visit him. He's been turned down flat, but he won't give up."

Chapman, 52, who was diagnosed as psychotic and denied parole four times, is still considered so dangerous and at risk from other inmates, he is confined to a special unit at Attica.
