While Tori Spelling's impending return to 90210 is certainly exciting, it's not the most pressing issue on the minds of fans.

We learned this week that Adrianna is pregnant.

Who is the father? Television columnist Korbi (from Zap2It) makes it rather obvious. In her latest Q&A, she responds to that question with:

Someone we know. Someone we haven't seen in a while. Someone who's super hot.

Gotta be Ty, right? Interestingly, he's played by Jessica Lowndes real-life boyfriend Adam Gregory - and he's confirmed to return to the show in the near future.

Did Ty and Adrianna share a night of unprotected passion?
