Mariah Carey is extending her sweet 16 celebration by enjoying a second week at the top of the US singles chart with her 16th number one, WE BELONG TOGETHER.

The R+B ballad has held off challenges from Gwen Stefani and Ciara for a second week to stay on top.

Meanwhile, 50 CENT's JUST A LIL BIT continues to rise up the Billboard singles chart at four, and the BLACK EYED PEAS' DON'T PHUNK WITH MY HEART rounds out the top five.
