New York Rangers star Brandon Prust has been caught red-lipped. After we reported yesterday that he’s been getting cozy with “Gossip Girl” star Michelle Trachtenberg, his beautiful girlfriend of a year, Marie-Pier Morin, who’s now in Canada, burst into tears, our source said. “He makes out with other girls all the time, like all the time,” said a different source who’s seen him lock lips with women at Gold Bar and 1Oak. An online forum, “Brandon Prust Sux,” delves into his alleged numerous romantic exploits. A rep for Prust said, “Brandon is not dating Michelle Trachtenberg. They just met. Other than that, Brandon has no comment.”
