Jennifer Aniston’s glowing, busty appearance had guests at the Glamour Women of the Year awards at Carnegie Hall Monday night buzzing that she may be pregnant. The star arrived with her boyfriend, actor and screenwriter Justin Theroux, and wore a billowy Versace black gown that showed off her curves, including an “incredible bosom” as described by one guest. Aniston also posed for photos, with her arm protecting any telltale signs of a baby bump, with Chelsea Handler, to whom she presented an award. Other witnesses spotted Aniston holding a glass with ice near the bar, but “no one saw her drinking alcohol.” She and Theroux later went to dinner at The Modern. But, late last month, Aniston knocked down persistent rumors she was starting a family with Theroux, telling Hello! that she was neither engaged nor pregnant. She explained: “It’s just I quit smoking, so I’ve gained a couple of pounds.” A rep for Aniston didn’t get back to us. Other glam guests at the event included Jennifer Lopez, Diane Sawyer, Jessica Alba and Tory Burch. [Page Six]
