Wild behaviour is Charlie Sheen's lifestyle, says ex-wife Denise Richards

Denise Richards has said that ex-husband Charlie Sheen's wild behaviour is just the status quo for the actor.

"This has been something I have dealt with for years. This is not a new situation," the New York Daily News quoted her as saying in an interview on ABC's The View set to air Friday.

The actress said she wasn't surprised by her ex-husband's recent antics, which came to a head last month when he landed in the hospital after partying all night with porn performers.

"You know, this is Charlie's lifestyle. He makes no bones about it... and it is what is," she said, according to Us Weekly.

Richards, who has two daughters with the actor, says shielding them from their father's behavior is a challenge and she wishes she could avoid.

"There are times where his life is more colourful than others, more public than others, and as the kids get older it's a difficult thing," she said.

"I have never had to deal with this and this was a subject I had hoped to talk with my children about as they got older. But it's hard," the actress added.
