It seems Kim Kardashian isn’t the only member of her family with an expanded waistline. The National Enquirer reports that brother Rob also is showing some belly. But at least Kim has pregnancy as an explanation. The Enquirer says Rob, 26, pulled his shirt off in the parking garage of a West Hollywood gym a few weeks ago (24 Hour Fitness? FlyWheel Sports?), whereupon a photographer quickly snapped a picture of his unwanted avoirdupois. The photographer claims Kardashian stole her camera’s memory card and hit her in the face. While no charges have been filed, the Enquirer says the cops are investigating a possible felony robbery charge. Meanwhile, that uh, reputable, source of news says Rob’s mom, Kris Jenner, is looking for the photog, hoping to pay her to back off.
