Rapper Nelly's ode to his jewelled teeth is still taking a huge bite out of the US singles chart - his GRILLZ tops the Billboard list for the second successive week.

But Nelly faces tough competition from BEYONCE KNOWLES' CHECK ON IT after the former DESTINY'S CHILD star's PINK PANTHER movie tune jumps up to number two on the Hot 100 chart - becoming the list's greatest airplay gainer in the process.

Former number one act Chris Brown falls from two to three and Mariah Carey's DON'T FORGET ABOUT US and THE PUSSYCAT DOLLS' STICKWITU round out the new top five.

Meanwhile, GAVIN DeGRAW's WE BELONG TOGETHER is the charts highest debut, entering at number 38.
