Bruno Mars is Locked Out of Heaven at the top of pop charts

Bruno Mars is back at the top of the Billboard pop charts with his Locked Out Of Heaven hit.

The track has hit number one on the Billboard Hot 100 countdown in its 10th week on release, ending Rihanna's three-week reign as queen of the charts with Diamonds, which slips a spot to two.

Ke$ha's Die Young holds at three and The Lumineers' Ho Hey climbs a spot to four on the new chart. Maroon 5's former nine-week Hot 100 number one, One More Night, rounds out the new top five.

Meanwhile, Taylor Swift has climbed back to the top of the album charts as last week's number one, Alicia Keys' Girl on Fire, plummets to seven.

Wiz Khalifa's O.N.I.F.C. debuts at number two, while Rod Stewart's holiday album Merry Christmas, Baby holds firm at three.
