Justin Timberlake and Anna Kendrick have been seen together a lot lately; in J.T.'s new video for his hot new song, and now together at Cannes to promote the movie "Trolls".

I have never really thought of these two together for a duet, but it is simply amazing. I mean anyone with Justin Timberlake would sound good, but I forget sometimes that Anna does have some serious pipes too. Plus the fact that this song  is one of my top 10 favorites and boom!
