Wedlocked (1994)

Chris Gilchrist is a best-selling author and expert on marriage. Unfortunately, he's also single. Making an expedient decision, he hires a model to pose as his wife for the cover of his book. Now, two years later, he's been offered a lucrative television series - on the condition that his 'wife' appears on the show with him. Now, the hunt is on for the model who posed for the original photographs. Her same is Susie, she's a single mother herself, and the pair have absolutely nothing in common-except that they must prove to the world that they are perfectly, happily married.
