90210 0410 2 cw '90210' Season 4 pictures: Naomi's college kick off party and the newlywedsThe fun never stops for the now graduates of West Beverly Hills High.

The CW has released production stills from the season opener for “90210” in which Naomi (AnnaLynne McCord) throws herself a college kick-off party at her new mansion. In true Naomi fashion, she pulls out all the stops including a performance from rapper Theophilus London.

It was quite the suspenseful conclusion to last season. Adrianna (Jessica Lowndes) chooses not to hurl herself off a cliff. Liam (Matt Lanter) decides he needs time away from Annie (Shenae Grimes) so he hops on a fishing boat. Raj (Manish Dayal) and Ivy (Gillian Zinser) get married. And if that wasn’t enough, Naomi is pregnant with Max’s (Josh Zuckerman) baby.

Just another day in Beverly Hills.

The series returns September 13 at 8 p.m. ET.
