Actress Katherine Heigl's husband-to-be is begging the KNOCKED UP star to quit smoking as a wedding gift to him. Singer-songwriter Josh Kelley will wed Heigl in her native Utah at Christmas (07), and he hopes she'll have stopped smoking by then. A friend of the couple tells Life + Style magazine, "He's been pushing her to quit for a while but realised he needed to give her a deadline. Josh thinks it's a nasty habit. "Katherine adores Josh and wants to make him happy, so she's determined to succeed."
