Wedding bells for Bilson?

Former 'The O.C.' actress Rachel Bilson - who started dating actor Hayden Christensen after meeting on the set of 'Jumper' in 2007 - has been enjoying a break with Christensen's family and onlookers overheard the actor's grandmother calling Bilson her "future granddaughter".

The couple were joined by Christensen's grandparents and Bilson's grandmother at New Jersey's Virginia Hotel where "they all had cocktails on the front porch every night".
