Paris Hilton Doug Reinhardt sunglasses LAX airport

And perhaps for a V-Day engagement too?

Yesterday afternoon Paris Hilton and Doug Reinhardt returned to Los Angeles from France, and even though they were on a plane for over 10 hours, the lovebirds looked well rested and ready to go!

We're guessing Paris already has her Valentine's Day plans laid out, but what's Doug got up his sleeve? I guess we'll find out soon enough...and probably from Paris' Twitter!
