Lyrics anyone?

Anyone remember a song from like 2 or 3 years ago in the summer, it featured a guy, it was sang by a hispanic girl or something and shes telling the guy to call her cause she misses him or something and when the guy sings or raps hes saying that hes busy and moving from hall to hall or something. I know the details are REALLY random and all over the pace but I need the song for an ignment and Ive been wracking my brains to remember but I cant.
