The sexy video stars singer- actor Zendaya who herself is a huge Bruno Mars fan . Bruno and Zendaya are apartment neighbors what give each other flirty looks in the hallway as they are entering their respective places . The singer then serenades the lady from her own pad separated by a wall , as Zendaya sings along , slowly unzipping her Versace dress . The video concludes with Zendaya ’ s gown literally hitting the floor . A “ The End” screen then flashes with a knock on the door so we can run our imagination wild .
