Rapper Flo Rida has scored a 10th week atop the U.S. singles chart with his cool anthem Low. The hitmaker cracked the top of the Billboard Hot 100 at the beginning of the year (08) - and he has been there ever since, keeping the likes of Alicia Keys, Rihanna and Chris Brown away from number one. But reported couple Brown and Rihanna are still Flo Rida's leading competition - Brown's With You and Rihanna's Don't Stop The Music remain at numbers two and three respectively on the new countdown. Meanwhile, Sara Bareilles' Love Song jumps up from five to four, switching places on the new chart with Alicia Keys' No One. Country icon George Strait scores the week's highest debut, entering the Hot 100 at 54 with I Saw God Today. And Paula Abdul is back in the charts for the first time since 1995 - Dance Like There's No Tomorrow, the pop star's collaboration with fellow American Idol judge Randy Jackson debuts at 80.
