The proof is on the finger

Since news broke of Rachel Bilson and Hayden Christensen's engagement, we've all been wanting a glimpse of the ring.

But after attending a string of New York fashion week events, Bilson didn't deliver the goods, showing up with either a ring-less finger or a covered up hand.

Now back on the west coast, the actress was spotted at her local supermarket, and I'm pleased to say there was a prominent new piece of jewellery on her left hand.

So there you have it - it's official!
