British pop star Harry Judd has offered to take a lie detector test on Oprah Winfrey's US talk show to prove he slept with Hollywood actress Lindsay Lohan.

Judd, the drummer in British pop act McFly, boasts he slept with the Mean Girls star while they were filming Disney comedy Just My Luck together last year, but Lohan has consistently denied his claims.

He pledges, "I'll go on Oprah with Lindsay and do a live lie detector test. That'll prove who's telling the truth."
