Actress Kristen Stewart apologized to long-term boyfriend and "Twilight" co-star Robert Pattinson on Wednesday (July 25) for a recent fling in which she was photographed kissing and embracing the director of her most recent movie, Rupert Sanders.<br/> <br />The 41-year-old director of Stewart's film, "Snow White and the Huntsman," also issued a statement on Wednesday saying he was "utterly distraught" over the pain he has caused to his wife and children following his indiscretion with the 22-year-old actress that made headlines around the world.<br/> <br />"I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected," Stewart said in a statement to People magazine.<br/> <br />A fling between a Hollywood star and her director is nothing new in showbiz, but this one gained widespread attention because of the high-profile people involved. Stewart, 22, and Pattinson, 26, portray the vampire-human couple of the "Twilight" series of blockbuster romance movies who are deeply in love in the films.<br/> <br />The pair's on-screen romance transferred to their real lives, and they confirmed they were dating in 2010. But they have tried to remain discreet in public and don't often discuss their relationship.<br/> <br />Representatives for Stewart and Pattinson did not respond to Reuters' request for comment.<br/> <br />John Russell, Reuters.
