Following a short trip out of town earlier this week, recently engaged actress Rachel Bilson is back home in West Hollywood.

The former "OC" starlet was accompanied by her family, as the well-clad group was spotted leaving the house and heading to the London Hotel on Friday (March 13).

As for the big engagement with fiance Hayden Christensen, the couple have remained mum on the issue, doing their best to maintain privacy.

And while there's still those who question the validity of the relationship - which kicked off while filming "Jumper" alongside one another - Rachel's been spotted sporting a big diamond that says otherwise.

Enjoy the pictures of Rachel Bilson heading out to the London Hotel (March 13).
