Stars Amanda Bynes and Jennie Garth share a birthday. Garth was born April 3, 1972 and Bynes was born April 3, 1986.
For over half of the first season, Jennie Garth was pregnant. Most of her scenes only showed the top half of her or showed her sitting down, behind a couch, etc.
Amanda Bynes made one reference to her time on The Amanda Show (1999). Holly is watching a clip of herself (a young Amanda Bynes) do stand-up and comments, "That girl should have her own show."
The opening theme song, performed by Lillix, was remixed for the Season 2 opening titles. The theme now lasts just under 40 seconds.
Several of Jennie Garth's former co-stars from Beverly Hills, 90210 (1990) guest starred over the course of the series. Ian Ziering (Steve Sanders) appeared in a season one episode as a client of Val's, Luke Perry (Dylan McKay) appeared in a handful of episodes in the third season as Todd the plumber, and Jason Priestley (Brandon Walsh) was in a couple episodes in the final season. Rebecca Gayheart also appeared on Beverly Hills 90210 (1990) as a guest star.
