Overview: Pop star Wendy Wilson and her husband, Dan Knutson, make history as the first celebrity parents to enlist Supernanny's help. Wendy, who rose to fame as part of the multi-platinum trio Wilson Phillips, is now a stay-at-home mom working on being the best mother possible after having four sons in five years. As the daughter of Beach Boys' Brian Wilson, she was raised in a household where the children had few boundaries, and is often a pushover with her rambunctious toddlers, Leo, 4 and Beau, 3. Husband Dan, a former rock singer, was raised just the opposite way, with clear-cut rules and a strict schedule. Having had twins Willem and Jesse just six weeks prior to filming, Wendy and Dan are exhausted, overextended, and realize that their current parenting style won't work.
