Justin & Mila Run for Fun on Set

Sept. 2 2010, Published 3:00 p.m. ET
These two always seem to be having so much fun on set! Mila Kunis and Justin Timberlake made a run for it on the set of their new flick, Friends With Benefits in L.A. on Tuesday. We don't think we've ever seen them with anything but a smile on while shooting scenes in NYC, and it seems that grinworthy way to work is going to carry over to the West Coast!
