The Hollywood hunk - who appears in the film alongside his former fiancee JENNIFER LOPEZ - was scheduled to join director Kevin Smith and his young co-star Raquel Castro on the red carpet tonight (02JUN04).
And friends of the actor are worried the hectic workload he's taken on in the aftermath of his split with J.LO and her blossoming relationship with new boyfriend Marc Anthony are playing havoc with his well-being.
One pal tells Britain's DAILY STAR newspaper, "Ben has been watching all the speculation about Jennifer and her new boyfriend Marc Anthony and is very aware that people want to talk to him about it and get his slant.
"It is coincidental that he's poorly at the moment and he's hoping to recover soon. He has been focusing on his career as an actor since splitting with Jennifer. The fact that she is his co-star in Jersey girl would only fuel people to pry."02/06/2004 02:40
