Which Two A-List Celebrities Were Caught Kissing in the Street? (PHOTO)

It’s Keira Knightley and Mark Ruffalo! To be fair, Keira and Mark were snapped while filming a scene for their upcoming film Can a Song Save Your Life? The movie, co-starring Hailee Steinfeld and The Voice’s Adam Levine, is currently shooting in New York.

These two have been spotted together daily, but sadly, there is no real-life love story on the in the making. Keira is engaged to Klaxons keyboard player James Righton, and Mark is married with three children.

It looks like they’ll generate some major heat on-screen, though!
