Are Rachel Bilson and Adam Brody Dunzo?

Uh oh! The rumours surrounding the end of Rachel Bilson and Adam Brody's "cutest ever" relationship are coming in a bit too quickly. Last week we told you about Zach Braff getting between Rachel and Adam, and now comes word that Rachel has been spotted with former 'N Sync-er, JC Chasez, according to My Kinda Place.

Rachel Bilson was spotted out with JC Chasez (formely of NSYNC) this week, fuelling rumours that she and the gorgeous Adam Brody are on a break. Last week the foxy actress was spotted partying with bachelor-about-town Zach Braff, so she's definitely not helping to put Adam's mind at ease.

And as Life & Style reports, Rachel and JC were even spotted out on a double date with Justin Timberlake and Cameron Diaz.

Rachel has been painting the town on both coasts with former 'NSync singer JC Chasez, 30. The two first hit the scene in late August, partying in NYC at the MTV VMAs. Then on Sept. 19, Rachel and JC double dated with Justin Timberlake and Cameron Diaz.

Yeah, I'm thinking all signs are pointing to DUNZO. Which is too bad, cuz you know, it's Seth and Summer. Of course, if Rachel Bilson is single, well then maybe, just maybe... I would still have absolutely no chance with her. Maybe I should move to LA and pretend to be gay. That seems to have worked for other bloggers...
