Wedlocked was an Australian sitcom that ran for 11 episodes in 1994 on the Seven Network. It was created by Andrew Knight and Doug MacLeod.
Chris Gilchrist, a best-selling author and expert on marriage, is actually single. He hired a model to pose as his wife for the cover of his book but when he is offered a lucrative television series on the condition that his 'wife' appears on the show with him, he asks the model who posed for the original photographs to continue the ruse. Susie is a single mother and the pair have absolutely nothing in common, but they must prove to the world that they are happily married.
