Charlie Sheen and Brooke Mueller in 'Paradise'

Aug. 22, 2011 — -- The story of Charlie Sheen and Brooke Mueller just got a bit more bizarre.

After reportedly flying Mueller out of a Mexican drug rehab clinic and setting her up with Los Angeles doctors, Sheen whisked Mueller back below the border, and they're enjoying what looks like a romantic getaway.

Photographers snapped the couple kicking back in a hammock, drinking what appear to be bottles of water beach-side, and pretending to smoke bananas. Far from the antagonistic couple they've been for most of the year, Sheen, 45, and Mueller, 34, look like love birds. Sheen's happily chirping away as well.

"Forgot how much I love this place. #mexico is paradise...." he tweeted Sunday. "Brooke and I are thinking about staying for the rest of the month!!!"

It's not clear who's taking care of the couple's twin sons, 2-year-old Max and Bob, while their parents are in Mexico. Representatives for Sheen and Mueller did not immediately respond to ABCNews.com's requests for comment.

The Mexico trip is the latest in what's been an interesting summer for the former "Two and a Half Men" star and his most recent ex-wife. In July, according to TMZ.com, Sheen flew Mueller out of the Mexican rehab clinic where she was said to be seeking treatment and set her up with the same doctors who treated his addiction issues earlier this year. Sheen reportedly footed the bill.

The Mexican treatment would have reportedly required Mueller to take the hallucinogen Ibogaine to help rewire her brain. Ibogaine is a psychoactive chemical compound that is illegal in the U.S.
