Coco Arquette is getting a baby brother! Breaking Celebrity News can exclusively reveal that David Arquette and his girlfriend, Christina McLarty, are expecting a son.

McLarty -- who Breaking Celebrity News can reveal is currently five months along, and not four, as has been reported -- was practically glowing with baby joy as she and her boyfriend attended a Flaunt magazine party in Miami on Thursday night. Appropriately, McLarty was dressed in blue as Arquette happily pointed at her bump with his arm around her waist.
