After entering rehab last month, Brandon Davis is back to his old habits. The Davis family is said to be very upset with the young heir, who pushed him to enter rehab in order to mend his tarnished reputation. Brandon has been sighted at clubs and now he is on his way to St. Tropez with pal Paris Hilton. One L.A. wag in Alcoholics Anonymous said, "He is not serious about getting sober." Question is how could one be sober when you are off to a city that drinks champagne as water? Let’s be real, people in St. Tropez use champagne to rinse their face, I am pretty sure its not going to be that challenging.
