Are these two ever gonna get hitched?!

The infamously on-again-off-again couple, Rachel Bilson and Hayden Christensen, grabbed breakfast together Friday but maybe there was something wrong with the eggs??

I mean yes, there are photographers around but is that any reason not to hold your boyfriend's hand? Any reason not to cuddle up with your girl? Any reason not to smile?

Note to Hayden and Rachel: The couple that smiles together, stays together.
