Do you think it might have come from Cam's current (and Jen Aniston's former) squeeze Paul Sculfor? Cammy turned 36 on Saturday, so the ring might have been an especially thoughtful birthday present - though we wouldn't be surprised to learn that Paul popped the question to his super-hot girlfriend, either!
