Mark Salling wasn’t full of “Glee” at LA’s Supper Club the other night. The actor arrived at 1 a.m. with friends and threw a tantrum when there wasn’t a table for him at the Jeep/Maxim party. A witness said, “All the celebs were sitting together, but Mark wanted a table to himself. Staff suggested he share a table with [‘The Hills’ star] Lo Bosworth, but he scoffed, ‘Are you kidding me? We’re leaving.’ ” Guests who were fine with their seats included Jamie Kennedy, Mel B. and Dominic Monaghan. Despite video of him at the club, Salling’s reps claimed, “Mark never went to that party or the venue that night at all.”
