Charlie Sheen's latest problems with drugs and sex are well-chronicled by now, but remain a hot topic of conversation and the butt of many a joke. So it was no surprise when Denise Richards, Sheen's ex-wife and the mother of his two children, received a Sheen-related grilling while guest-hosting 'The View' (Weekdays, Syndicated on ABC).

The hosts, led by Barbara Walters, seemed on a mission to get Richards to say something, anything, interesting about her troubled ex, but she didn't give them much. Does the latest trouble surprise her? "It doesn't," said Richards. "This is Charlie's lifestyle, he makes no bones about it."

The hosts pressed on, even after Richards said it wasn't her place to make a judgment about Sheen's behavior, which has shut down production of the popular sitcom 'Two and a Half Men.' "Is he an addict?" asked Joy Behar. "He's an addict, right?"

"You should have him on the show and get into detail, what's going on," said Richards. "My concern is our kids."

Barbara Walters asked what Richards tells her young children about Sheen, and Richards said she has used a couple of books to help explain, but didn't want to go into detail. "What can you say?" said Richards. If this TV appearance was any indication, not much at all.
