“Community” star and E! “The Soup” host Joel McHale had invited some powerful figures to his 40th birthday party at LA’s Redbury Hotel. He joked with a Remy V cocktail in hand: “I invited Obama . . . and the Queen of England. But she is at a premiere in Japan.” He was toasted by Jimmy Kimmel, Adam Scott and Jenna Fischer. As a joke, his birthday cake read, “Happy Birthday Matthew Lillard,” as he’s always mistaken for the star of “The Descendants.”
