Usher has kept his crown as the king of the U.S. pop charts for a third week. The singer's "Love In This Club," which features Young Jeezy, has spent all of March at number one on the Billboard Hot 100.

Chris Brown's "With You," Flo Rida's "Low," Sara Bareilles' "Love Song" and "Don't Stop The Music" by Rihanna make up the remainder of the new top five, after all refusing to move from last week's two to five spots.

British phenomenon Leona Lewis' much-hyped appearance on TV show Oprah helped the singer land her first top 10 hit - Bleeding Love rockets up the charts from 21 to eight.

Rap mogul Sean 'Diddy' Combs' all-girl group, Danity Kane, score the new chart's highest debut - "Damaged" enters the chart at 64.

Meanwhile, Alan Jackson scores his 23rd number one hit on the Hot Country Songs chart with "Small Town Southern Man."
