No one will ever forget Charlie Sheen's spectacular meltdown in 2011 when he declared himself a "warlock" full of "tiger blood" and "Adonis DNA" who was surrounded by porn-star "goddesses" and in a constant state of "winning!"
Sheen, 47, has been in and out for rehab for decades, including multiple attempts to get sober in 2010 and 2011, and a much-publicized attempt in the late '90s after his dad Martin Sheen (a recovering alcoholic himself) turned his son in for violating parole following a cocaine overdose 1998. Then there was Sheen's infamous Christmas Day 2010 fight with former wife Brooke Mueller (who's also a recovering addict), which got him another 30-day stint.
Just don't expect Sheen to be checking in again anytime soon. "I don't believe in rehab anymore," he told "Good Morning America" in 2012. "It's not for me. It's not for everyone. It's not a one-size-fits-all and it didn't fit me."
