Bobby Brown claims he had sex with a ghost

Bobby Brown believes he had sex with a ghost.

The singer, who was married to Whitney Houston from 1992 to 2007, opened up about his intimate ghoulish experience in an interview with US TV show, 20/20.

"I bought this mansion in Georgia ... this was a really, really spooky place," Brown said.

"But yes, one time, I woke up, and yeah, a ghost. I was being mounted by a ghost."

Brown, who has spent time in rehab in the past, maintained he was sober at the time.

"I wasn't high," he said, "I was not trippin'".

Brown's not the only high profile person who has claimed to have had sex with a ghost.

Four years ago Kesha told radio host Ryan Seacrest that she wrote her song Supernatural after hooking up with a ghost.

"It's about experiences with the supernatural ... but in a sexy way ... I had a couple (of) experiences with the supernatural," she said.

"I don't know his name! He was a ghost! I'm very open to it."

In the 20/20 interview, Brown also opened up about his relationship with the I Have Nothing singer and revealed that he first saw Houston snorting cocaine on their wedding day.

"She did drugs, but drugs didn't do her," he said.

"She knew how to handle herself. It only made me, you know, love and want to protect her more at the time."
