Brad Pitt is reportedly forced into rehab as he's beaten down by his bitter divorce and custody battle against Angelina Jolie. Rumor has it, the "Allied" actor recently attended a drug and alcohol program amid his battle with addiction.

According to the National Enquirer, Brad spent a whopping $15,000 on a five-night sober retreat in a private suite inside Casa Del Mar, a luxurious five-star resort in Santa Monica, California, where he allegedly attended a "Narcotics Anonymous" group party on January 22.

Some photos obtained by the site showed Brad sneaking out of a nearby hotel's backdoor while carrying a bouquet of balloons from a "Sexy Sober Sunday" event.

"Brad's benefitted from the principles and rules that come with dedicated sobriety, and he's found a way to celebrate it, too," a source claims, "His friends have been key in helping him see the positives from clean living, which is why they arranged this sober divorce party!"

"[He] doesn't want any part of drugs or booze right now; he's dedicated to his children. It's what's best for himself and his family in the long-term and that's a bigger buzz than any cocktail or marijuana joint could provide. Brad just wants to lead a healthy and sober life - with his kids," continues the source.
