Mel Gibson, Formula One heir Petra Ecclestone and her new husband, James Stunt, sparked a champagne frenzy at Beacher’s Madhouse in LA last Wednesday night, spending a whopping $250,000 on Cristal — with Stunt picking up the tab. They went wild even though neither Gibson nor Stunt drinks alcohol. A spy said, “Neither of them touched a drop, they were handing it out to everyone else.” Gibson, whose battle with booze is well-documented, arrived with Ecclestone and her hubby in their Rolls-Royce and was “pretty relaxed and chilled.” The star ignored women around him before the threesome left near 2 a.m.
