Charlie Puth is officially the king of addictive, can't-get-them-out-of-your-head pop duets. After killing it on Wiz Khalifa's "See You Again," [1] and making sweet, sweet aural love on his song "Marvin Gaye" with Meghan Trainor [2], Puth has a new duet partner: Selena Gomez [3]. If you're still having trouble forgetting about an ex, their song "We Don't Talk Anymore" is the perfect listen, and a total guilty pleasure. Check it out above, and scoop up his album Nine Track Mind when it comes out on Jan. 29!
