Goff/INFphoto.comThe Sun is reporting that Amy Winehouse is back in rehab. Apparently she went out for a "heavy drinking session" and the next day went to rehab. Obviously she had a good night. Reports are also saying that the decision to go to rehab was influenced by her new boyfriend, Reg Traviss, so that means it must have been a really good night. Traviss wants her to "quit alcohol for good." She must really like this guy. But if she can't quit and they don't work out, she'll always have St. Lucia.
