Samantha Who?:

When Sam starts dating rock superstar Tommy Wylder (Duran Duran's John Taylor) - an idol from a youth that she has no recollection of - she becomes so embarrassed by Andrea and Dena's fan-like reactions that she unintentionally begins to alienate them.

Meanwhile, with Sam dating Tommy, Regina fondly recalls memories of Howard's early days as a musician and gets all hot and bothered when he takes up the guitar again. During a concert Sam remembers her fanatical obsession with Tommy in the past and becomes a slavering fan again, which Tommy doesn't appreciate. Dena is so annoyed by Sam's behaviour, she tries to uninvite her from her dog, Mr Cellophane's, birthday party, which Howard performs at with his band.
