Beyonce Knowles is back at the top of the US singles chart after toppling rapper Nelly with her PINK PANTHER theme CHECK ON IT.

The sexy former DESTINY'S CHILD star's new number one is also the Billboard Hot 100's greatest airplay gainer, and also claims the top spot in the Pop 100 and the Hot Digital Songs charts.

Nelly's GRILLZ slips to number two and Chris Brown's former chart-topper RUN IT! stays at three.

British singer/songwriter JAMES BLUNT scores his first top 10 hit after YOU'RE BEAUTIFUL climbs from 15 to eight. His album Back To Bedlam entered the album chart top 10 yesterday (25JAN06).
