Matt and Jen: Hot New Couple?

Are Jennifer Garner and Matthew McConaughey an item?!  Did Matt grow out his hair?   What's going on???  You can relax, the two are faithful as ever to Ben and Camila, they're just shooting a movie!  Jen and Matt are on location in the Boston, Mass area to film their new movie The Ghosts of Girlfriends past.  Believe me, I'm also relieved that Matt's hair doesn't really look like that!
