Justin Timberlake & Mila Kunis: Kissing at Grand Central!

Justin Timberlake puckers up with co-star Mila Kunis on the set of their new movie, Friends with Benefits, inside New York City’s Grand Central Station on Saturday (July 31).

The romantic comedy, which costars Woody Harrelson and Emma Stone, is about relationship between two friends that gets complicated when they decide to get romantic.

It also looks like Justin gets down on one knee to proclaim his love for Mila! Marriage proposal, perhaps??
