According to a TMZ report, the "Two and a Half Men" star, 45, was seen taking shots of Grey Goose vodka alongside a female companion during an outing at The Palms hotel in Las Vegas Monday.
What's more, according to a witness, the actor — who was staying in the $40,000-a-night Hugh Hefner Sky Villa inside the hotel's fantasy tower — was complaining to fellow bar patrons that CBS execs have been urging him to go to rehab.
