Name of new song (2010/2011) with a girl singing and a saxophone in the back (not calabria or infinity)?

there was this song i heard on the radio as i was on vacation and it had this really catchy tune but they never said who it was by or the name so ive been trying to figure it out ever since. the sax part goes something like da dada daa do do do do do da do da daa (hard to do on keyboard)
