Charlie's Bahama Mamas Brooke and Goddesses

Charlie Sheen boarded his private jet this afternoon along with his two new girlfriends and ex-wife Brooke Mueller ... and took off for an island near the Bahamas for a private adult vacation ... TMZ has learned.

Sources close to Sheen tell us ... the actor, his porn-star GF Bree Olson, model Natalie Kenly and Brooke will spend the next few days together ... sans Charlie's kids.

Remember, Charlie is expected back on the set of "Two and a Half Men" on Tuesday.

Fingers crossed.
