Charlie Sheen and Brooke Mueller Reportedly Reconciling

Aug. 3, 2011 — -- They weathered an ugly divorce and an even nastier battle over their sons. But, it seems, Charlie Sheen and Brooke Mueller may be reconciling.

According to TMZ.com, last month the former "Two and a Half Men" star 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 is reportedly footing 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.

Back state-side last weekend, Mueller took a break from rehab to meet up with Sheen and their 2-year-old twin sons, Max and Bob. TMZ reported that Sheen wants Mueller to move closer to him when she completes her treatment so they can spend more time together with the kids. They also published a photo of the family smiling, the boys clutching candy in their hands.

It's a sweet turn of events, if true. Sheen's publicist declined ABCNews.com's requests for comment. Mueller's did not immediately respond.

Mueller, 33, has been in and out of rehab over the past year. Despite that, her custody agreement with Sheen, 45, reportedly does not require either of them to undergo drug testing.

Sheen famously lost his sitcom job after a January bender and told ABC News' "20/20" that he was "banging seven-gram rocks" of drugs while partying. Mueller has been to rehab multiple times.

The former couple's divorce became official on May 2. Since then, they've gone to court multiple times to hammer out details of their custody agreement regarding their sons. Mueller currently maintains primary custody of the boys.

The parents' history of drug abuse has come up often in the legal proceedings. In court papers filed before the March custody agreement, Mueller said she was struggling with her sobriety and attending a day program as well as living with a sober companion. She said her mother would assist her in caring for the children, according to the documents.

The documents also said that for a time in January before custody became an issue, Mueller and the twin boys lived with Sheen and his two then-girlfriends, Natalie Kenly and Rachel Oberlin.

Mueller, Sheen and the two girlfriends even went on vacation to the Bahamas together, but Mueller alleged that Sheen was drinking and his behavior turned violent. She said that Sheen punched her, threatened to stab her with a pen knife and spit on her feet, according to the documents.

Mueller said Sheen also told her that he "hated his ex-wife, Denise Richards, violently and he was going to have her hair shaved off," according to the court records.

Mueller and Sheen married in May 2008. In November 2010, he filed for divorce.
