Exclusive '90210' video: Annie and Liam's hot make-out session (whoa!)

Tonight's "90210" episode has a very special treat for Lannie fans -- and Zap2it has your exclusive sneak peek at Matt Lanter and Shenae Grimes in the sexy scene.

Despite Liam's erratic behavior lately, it looks like Annie's long-dormant feelings for him are resurfacing... and she's not exactly doing a great job of keeping her emotions to herself. Perhaps that "50 Shades of Grey"-esque book that she's writing has gotten under her skin a little more than she expected!

We're not quite sure how this steamy sequence fits into the episode -- is it a dream? a momentary lapse in judgment? a hint that they could end up together after all? -- but we sure don't mind watching it. Over. And over. And over.

Tune in Monday night at 9 p.m. EST on The CW!
