Michael Jackson apparently thinks he's an 800-year-old British knight.
The eccentric singer reportedly checked into London's Dorchester Hotel as Sir William Marshal - one of the country's most legendary knights from hundreds of years ago.
A source told Britain's The Sun newspaper: "Michael likes to use various pseudonyms when he books into hotels. William Marshal appealed to him because he's such a huge fan of British aristocracy."
"He picked the name himself partly as a tribute and partly to divert attention from himself. He thinks that Lords and Ladies stay at the Dorchester all the time."
Meanwhile, the troubled singer was reportedly turned away from a star-studded bash at a London restaurant after he turned up too late.
The star - who is in the UK to record a Hurricane Katrina charity single - was told he couldn't enter the Hard Rock Cafe bash because it was too full when he showed up shortly after 11.15pm.
A source told Britain's Daily Mirror newspaper: "When he was told the party was a no-go, he didn't kick up a fuss, he just quietly left."
Jackson's publicist added: "Michael was disappointed he could not attend the party as he likes Hard Rock Cafes. He's like to come down to the restaurant before he leaves the UK."
