Over more than two seasons on 90210, Adrianna and Navid have survived a drug problem, a pregnancy, a cheating scandal... and another drug problem.

But the former's breakout career, combined with her diva-like attitude of late, appears to be too much for this couple. Last week, Navid admitted he his feelings for Silver - and, this week, a self-centered holiday party thrown by Adrianna may finally drive her man into the arms of her friend.

"Silver's there for me when Adrianna should be," Michael Steger told TV Guide. "Ade's turned into someone else. It's just too much for Navid to handle, so he's totally disconnecting from the relationship."

Jessica Stroup wouldn't divulge much about her character's future with Navid, but said there's "lots of kissing" this week and some "good stuff" ahead in 2011, including "a little bit of the physical."

On tonight's episode (the final one of 2010, previewed HERE), Adrianna will host a shindig that includes an ice-skating rink and elves. But it won't end well for this singer, as Victor exposes her song-stealing secret.

"Just when she thinks everything's going amazing, she realizes that Victor has now turned on her and she's devastated," Jessica Lowndes says.

But let's get back to the personal for a moment. Sound off now, 90210 fans: With whom do you wanna see Navid?
