Nothing says "New Romance" like smeared lipstick on your check!
The co-stars were caught by a mob of fans and some photogs while
sucking face trying to leave the wrap party for their new flick, The Mortal Instruments: City of Bones together in Toronto Saturday night.
We think it's safe to say these two are officially a serious couple!
The duo has been seen looking dreamy-eyed and love-stricken since the moment they met.
The fact that their Mortal Instruments characters are star-crossed lovers only makes this romance even more adorbsies!!
