Welcome back to El Lay, Rachel Bilson??
Seems like everyone and their mother is booking it on a plane as of late!
The Hart of Dixie actress landed back in El Lay and was spotted all by her lonesome at the airport on Monday!
But if that makes you sad, don't you worry your pretty little head! This lucky lady is still dating her hunky bf Hayden Christensen, so she's probably heading home to see her man!
Even though we haven't seen them together as often as we'd like, we srsly cannot believe the adorable duo have been together since 2007!
That's like, FOREVS in Hollywood years!!
