It's Stephanie's 10th birthday. When Stephanie hears that Tommy Page, her favorite singer, is scheduled to be a guest on "Wake Up, San Francisco", she begs Danny to invite Tommy to her birthday party, but Danny refuses. What Danny doesn't want Stephanie to know is that he has arranged for Tommy to be at the party, but he wants to surprise Stephanie, and that's why he told Stephanie he wouldn't invite Tommy. After Stephanie's party begins, Danny brings Tommy home with him, and Stephanie is shocked. Stephanie just happens to have a monumental crush on Tommy, but Stephanie is devastated when she later sees Tommy and D.J. kissing. Stephanie declares war on D.J. for this, until Tommy helps straighten things out between them.
