Mila Kunis and Friends With Benefits co-star Justin Timberlake looked picture perfect at the movie's premiere in New York City.

The sexy twosome, who seem to have incredible chemistry on screen, had the flashbulbs going wild at the Ziegfeld Theater. We're not surprised ... they're hot!

Both stars will be soon be attending a military ball ... thanks to a couple gutsy YouTube requests from two Marines. Lucky!

Friends With Benefits hits theaters on July 22. See all the stars who attended Monday night's premiere in the gallery below. Check out Emma Stone's pink and red fashion choice ... after the jump.
