R 'n' B superstar Usher has lost his place at the top of the U.K. singles chart after a grime group scooped the crown this week. London hip-hop collective Roll Deep, which was co-founded by former member Dizzee Rascal, shot to number one with their track "Good Times", pushing Usher's "OMG" into second place.
Usher was also forced to settle for the second spot in the album charts, as "Raymond vs. Raymond" was toppled by Plan B's debut "The Defamation of Strickland Banks". AC/DC's "Iron Man 2" soundtrack claimed third place, while "Glee"'s Madonna tribute album, "Glee The Music: The Power Of Madonna", came in at four and Bullet For My Valentine's "Fever" rounded out the top five.
"OMG" was doing better Stateside, continuing its climb to number 6 as of last week.
