There’s going to be trouble in paradise on 90210.

Keep reading to find out Adrianna’s shocking news.

Teen love between Adrianna (Jessica Lowndes) and Navid (Michael Steger) will turn into teen angst in upcoming episodes of the CW show.

Adrianna, the recovering drug addict, will be dealing with a teen pregnancy, according to a source close to the show. But is Navid the daddy? It’s anyone’s guess since he recently revealed he’s a virgin.

Meanwhile, Adam Gregory will return to West Beverly High, the insider says. Gregory played the sexy Ty Collins who wooed Annie (Shenae Grimes) by flying her to San Francisco for a first date. Ty will stir up trouble for one of the show’s leading ladies. But is it Annie, who’s now officially — and openly — dating Ethan?

Answers to come — but you’ll have to wait for the return of 90210 on Jan. 6, 2009.

Tell us: Who is the father of Adrianna’s unborn baby? And who will regret Ty’s return?Michael Desmond/CW
