A Valentine Carol (2007)

Ally Sims is a cynical, superficial radio talk-show hostess in Seattle who doesn't know the meaning of love despite the fact that she gives love advice over the airwaves and has a loyal fiancé named Matt who is tolerant of her busy lifestyle. Two days before her wedding, Ally is visited by the ghost of Jackie Marley, who shows Ally her boyfriends of the past, present--and future if she continues to live this stressful, shallow life.
