Rumor has it that a Hollywood socialite is pulling a Beyonce by wearing a baby bump prosthetic, because she is too shallow to admit she is not really pregnant. Pictured above are Khloe Kardashian, left, and Tia Mowry-Hardrict, who attended the West Coast premiere of the TV show The Oath.

Khloe, 33, was spotted shopping at Fred Segal in Los Angeles on Wednesday. She wore a designer maternity dress with a matching duster which she conspicuously pulled over her bump. Khloe and Cleveland Cavaliers player Tristan Thompson, 26, are expecting a girl.
