Actor Macaulay Culkin has signed up to be a contestant on the new series of British reality show CELEBRITY BIG BROTHER - and TV bosses are hoping he will reveal all about his friendship with Michael Jackson.

The HOME ALONE star, 25, was reportedly picked because of his troubled childhood and his relationship with pop star Jackson who was acquitted of child abuse charges last year (05).

A source at network Channel 4 tells British newspaper the Daily Star, "This is a great coup for us. And because of his friendship with Michael Jackson, you're almost getting two for the price of one.

"We were desperate to bag Macaulay because we want some big name Americans who will be controversial and have a chequered history.

"And he fits the bill nicely because so much has happened to him in his young life.

"But more importantly he has been privy to Jacko's private world at Neverland."

Culkin will reportedly join basketball star Dennis Rodman and Anna Nicole Smith on the show.
