VIDEO: Mark Cuban Defends 'Getting Into Bed' With Charlie Sheen

Dallas Mavericks owner Mark Cuban, who’s been talking business with Charlie Sheen about a possible reality show, told MSNBC's Mika Brzezinski Thursday he's got no reservations doing business with the former Two and a Half Men star.

Asked if he was “getting into bed” with the TV star, Cuban said, “In bed? Absolutely not! Charlie’s personal life is his personal life!”

The billionaire praised Sheen for his ability to manipulate the media and dominate Twitter in the wake of leaving Two and a Half Men, adding that he's had cameras following the enigmatic star around to gather content for a possible reality show.

Brzezinski said Sheen's "potentially not well" and asked Cuban, "Do you really want to get involved with something that could end quite badly? And do you really think it's the right thing?"

Cuban responded, "Mika, have you spent time with him? Is there something you know that I don't?

"Anyone who has gone through the pattern of behavior that Charlie has, there's unquestionable risks. There's no question, Mika, you've got to be concerned, and in all the discussions I've had with him and with the people around him, you know, they call it Sober Valley Lodge where he lives for a reason.
