Jim Carrey has a new hottie. The funnyman, who broke up with Jenny McCarthy in April, took in Wednesday’s performance of “Fuerza Bruta: Look Up” in Union Square with a gorgeous, younger modelesque blonde. They were protected by two brooding bodyguards. A source said, “His assistant called the theater to ensure security would be top-notch and no one was to approach him for pictures. They were very romantic and there was lots of hand-holding.” Carrey’s rep declined to comment.
