When 90210 premiered in 2008, Annie Wilson (Shenae Grimes) prided herself on staying true to her Midwestern values. How times have changed!

During the series' fourth season, Annie became an escort who later seduced a priest named Caleb (Robert Hoffman) -- a far cry from the wide-eyed transfer student she once was.

"Playing Annie this season was really hard for me because I had zero connection to her storyline whatsoever," Grimes, 22, admitted to Us Weekly at The CW Up Front event in NYC Thursday.

"To me, it seemed really off-base that my character would even be behaving that way, because she does come from a pretty solid family and there was never any mention of her reaching out to her parents at all for money or anything," Grimes lamented. "I mean, they had a house in Beverly Hills, her mom's living in Paris -- it's not like they're broke! So I couldn't really wrap my head around the thought process behind what was going on, so that made it difficult."

But fans of 90210 needn't worry -- Grimes is glad the series will return for a fifth season this fall on The CW. "Fortunately the actors who I was working with were amazing, so they kind of helped me connect."

Grimes also revealed that she hopes Annie reconnects romantically with Matt Lanter's Liam Court, despite the fact that he recently hooked up with Jessica Stroup's Erin Silver.

"I honestly would love to see Annie and Liam back together. Don't tell Jessica Stroup that I said that, but I was very jealous! I was like, 'Come on!' because the fans love it so much," Grimes told Us. "I don't know why, because me and Matt are such bros, so we don't even think that we have the kind of chemistry that everybody else thinks we do."

Grimes added: "He's such an amazing guy to hang out with on set .and he's been the best influence on [Annie] so far, I think. . . it seems like a safe bet."
