While debate among some fans of 90210 have centered around which former stars might show up in the famous zip code again, loyal followers of the new series have a more pressing question:

Will Adrianna keep her baby?

The character got knocked up by Ty during her days of drug-laden hook-ups. Now, she's back together with ex-boyfriend Navid and her baby bump is starting to show.

"Whether Adrianna keeps it or not, we still don't even know," Maeve Quinlan, who plays Adrianna's mom, told E!, adding that rumors of Adrianna handing over the newborn to Brenda for adoption might be premature. "What you're going to be seeing... is what is happening mentally, her decision process. I think you're going to be kind of surprised with what happens with her decision."

The fate of Adrianna's baby is on the minds of millions of 90210 viewers.
