90210 fans didn't meet him last season, but we got a taste of Liam's step-father on the season finale, as Matt Lanter's character was dragged away by a pair of military school representatives sent by his displeased step-dad.

Now, it looks like viewers will come face-to-face with the strict guardian in Liam's life.

John Schneider has been cast as Liam's step-father on 90210. The character is a a Beverly Hills plastic surgeon that will clash with his son again, starting on the second episode of season two.

Schneider is a TV veteran whose credits include CSI, Smallville, The Secret Life of the American Teenager and Nip/Tuck.

In fact, on the final series listed above, Schneider portrayed a porn producer that slept with Annalynne McCord's character, Eden Lord. That means he's sort of gone to bed with the same gal his step-son banged on 90210.

Creepy.
