sheentalks3711.jpg Charlie Sheen's future with CBS and Warner Bros. may be up in the air, but the 45-year-old actor is reportedly in talks with Mark Cuban for a new program on HDNet.

“It could be a talk show or a reality show," Cuban told ESPNDallas.com. "We're trying to decide. Right now, we're taping a lot of different things that he's doing and we'll try to figure it out. It's still not 100 percent certain ... We'll do something together, but it's not certain it will be a show. It'll come down to what he wants do and what his situation is. We'll just figure it out from there, but it's a unique opportunity, I'll say that."

After watching Sheen's live broadcast over the weekend, Cuban said, "Everybody wants to critique a Web show that got put together in a few hours. That's not the point. It gave him a chance to be himself and have some fun. The thing I like the most about Charlie is that he just loves to mess with the media. You guys fall hook, line and sinker."

The actor's Ustream show Sheen's Korner has been watched by more than 1.2 million viewers to date, and over 100,000 people watched it live on Saturday night. Sheen rambled on about the latest thoughts in his "warlock brain", and he even revealed a new tattoo on his left wrist that says -- you guessed it -- "WINNING."
