90210

Jessica Lowndes picked a great day to turn 22.

The 90210 star is featured on tonight's episode... alongside Joe Jonas! Indeed, Adrianna's rise to fame continues on "Mother Dearest," as she attends a party in Hollywood and chooses a fellow celebrity as her date over Navid. Ouch.

Lowndes, of course, was not meant to be a series regular when she first appeared on season one. But she's grown into a main player on the show and we encourage fans to send in birthday wishes now!
