@pagesix: Rob Rausch kept a pricey promise to Maura Higgins. Rausch, who won season 4 of “The Traitors,” and Higgins, who was the runner-up, both appeared on “Watch What Happens Live” Wednesday. During the episode, Rausch gifted Higgins a gorgeous Hermès Birkin bag. “Would you forgive someone if they bought you a Birkin?” Andy Cohen asked. “She says all it will take to be forgiven is a Birkin,” as Rausch put on a pair of white gloves and went to retrieve the iconic orange box, carefully unwrapping the handbag to cheers and hoots. “I knew I would win,” said Higgins. “This is my moment.” 📸: Peacock; GC Images
