Whitney discovers Zack and Lauren's betrayal...on her wedding day

Whitney and Zack are a vision of happiness as they coo over newborn daughter Dolly, but beneath the proud dad's beaming smile is a very nervous man.

Young Britney has discovered that he slept with Lauren. One word from her, and his family unit could be blown apart.

Savvy Whit soon picks up on Britney's anxiety, and incorrectly deduces that Dolly's arrival has left her feeling unsettled. Guilty to know the real cause, Zack suggests the schoolgirl is upset because their wedding has been postponed; a problem Whitney decides to solve by insisting their nuptials go ahead, as planned, that very day.
