Charlie Sheen is clearly not learning his lesson. The 'Two and Half Men' star is leaving Los Angeles Wednesday on a tropical vacation with his wife, his live-in porn star girlfriend and another woman, RadarOnline.com is exclusively reporting. Seems the TV star forgot that he's supposed to be in rehab and that his show is shut down as it waits for him to finish treatment.

RadarOnline broke the news earlier Wednesday that Sheen's ex-wife, Brooke Mueller, moved back in with the actor this past weekend. Also shacking up with them are porn star Bree Olson and "nanny" Natalie Kenly. And now, the whole crew is reportedly headed on a vacation to a private tropical island.

"Just when you think Charlie Sheen can't do anything else to make you shake your head in amazement, he finds a way to top himself," said David Perel, RadarOnline creator and executive vice president. We couldn't agree more.
