Bobby Brown's son Landon  has denied bedding Hollywood actress Lindsay Lohan - insisting the tawdry romance rumours are "off the wall".

The star of MTV reality show Rock the Cradle once claimed he had sex with the star in a club toilet at a private party in West Hollywood when he was 21 and actress/singer Lohan was 20.

He said, "Me and Lindsay got really, really close. She followed me to the bathroom during a private party, and, well, we basically got together."

But Landon is now denying ever having sexual relations with the Mean Girls actress.

He tells the National Enquirer, "This is wild. This is off the wall.

"My father had a concert going on. The club was on the lot. She was on the lot filming something I think. I wasn't dating Lindsay Lohan on the low.

"Nah man, I ain't had sex with Lindsay Lohan. And I ain't tell him (sic) I had sex with Lindsay Lohan either. Word is bond, if I slept with Lindsay Lohan, I would still be sleeping with Lindsay Lohan right now."
