Tara Reid is back to her partying ways in the French ski resort of Courchevel. The “American Pie” star knocked back Cristal with a group of pals Monday night at restaurant La Mangeoire before treating them to a version of “Hotel California.” A spy sniffed, “They must have ordered 14 bottles of Cristal. Tara tried to sing, [and] it was clear she doesn’t have a great voice.” Later, more booze was brought out in a makeshift coffin marked “Prohibition.” “Her group then took turns getting into the coffin for photos,” our spy added. Reid’s rep didn’t get back to us.
