“Bridesmaids” star Kristen Wiig celebrated her 38th birthday on the Queens set of her new movie, “Imogene.” The comedienne was presented by the film’s crew with 100 doughnuts, a spy said, which were piled high like a cake. The rest of the cast — including Annette Bening, Matt Dillon and Darren Criss — gathered to sing “Happy Birthday.” No word on how many doughnuts they plowed through. Wiig plays a writer who fakes a suicide attempt to win back her boyfriend.
