Rachel Bilson & Hayden Christensen -- NEW COUPLE ALERT!

Whoa there, young Jedi! Remember those pictures of Jumper co-stars Hayden Christensen and Rachel Bilson holding hands? Well, now, it all seems a little bit too real.

Rachel and Hayden (both 25) were spotted spoon feeding each other lunch at neighborhood café Madame Matisse on Wednesday afternoon in L.A., passing food back and forth and giving each other plenty of eye contact. Why? Because that’s what lovers do.

Rachel‘s gal pal did come along as the third wheel but like any third wheel would, she talked on the phone most of the time and kept out the couple’s conversation.

At the end of their lunch date, Hayden even drove Rachel‘s car back to her house in L.A.

Now if this doesn’t smell like a brewing romance, I don’t know what will!

HAYDEN CHRISTENSEN <3 RACHEL BILSON

(Fashion note: Rachel is wearing an H&M dress.)

Rachel ended her three-year relationship with The O.C. co-star Adam Brody, 27, back in December 2006. Hayden was also “romantically linked” with Sienna Miller while filming Factory Girl. Jumper is set for a Feb. 15, 2008 release.

UPDATE :: Hayden and Rachel were spotted grocery shopping together on Thursday morning.
