Tiffany Hines may have lost her place on The CW hit Nikita... via a hydrofluoric acid bath, but she hasn't left the network. Tiff, who "killed it" as mean girl assassin Jaden, will recur on 90210 Season 4 as Kat, a police officer who may have something to do with Naomi's (AnnaLynne McCord) upcoming arrest.

Don't miss the 90210 Season 4 premiere on Tuesday, September 13!
