Whoa.

We already knew about Rumer Wills' guest-starring stint on 90210. She'll come aboard the show as Gia, a lesbian student that works on the school newspaper.

But new information has leaked out about the episode in which Willis will debut: the September 15 installment of the show will be titled "To Sext or Not to Sext." A major storyline in it?

The rumor that a series of Annie Wilson nude photos exist!

An Annie Wilson naked picture controversy is coming. Is this a good storyline? Sound off on it in our 90210 forum!

It's now evident what AnnaLynne McCord meant when she said this week that "Naomi gets ahold of some material that she uses around school to blackmail Annie." Did Wilson actually go all Vanessa Hudgens at some point? Or does Naomi create this scandal out of nothing?

We'll need to tune in to find out.

For now, click on the images below for a handful of pictures from the season's second episodes. The images feature Willis, new star Trevor Donovan and more...
