Lilo and S.Ro have been spending the latter half of the summer jetting back and forth from New York (where Lindz has begun shooting Ugly Betty).

Photogs spotted the couple of about one year headed for a Friday afternoon flight at LAX, not before stopping at Taco Bell (hey, a girl has to eat!)

They haven't even officially (come out) yet, but are they ready for marriage? News of the World seems to think they may be walking down the aisle, Lilo in Chanel, S.Ro in a suit, natch, sometime later this year!

Lindsay DOES refer to herself occasionally as Lindsay that gay marriage is legal in California, is she gonna make it official???
