R&B singer Usher climbed to the top of the U.K. singles chart on Sunday with "OMG," a song featuring rapper will.i.am from the Black Eyed Peas.

"OMG" moved up one place to dethrone "This Ain't A Love Song" by British band Scouting for Girls, the Official Charts Company said. It marks Usher's fourth UK number one single.

In the albums chart, Plan B -- the stage name of London actor/singer Ben Drew -- entered at No. 1 with "The Defamation of Strickland Banks," while Scouting for Girls debuted at No. 2 with "Everybody Wants To Be on TV." Last weekend's champion, Lady GaGa's long-running success "The Fame," fell to No. 3.
