Vickers debut hits top of charts
Diana Vickers has hit the top of the British singles chart with her first solo release.
The former X Factor contestant's debut single Once went straight to No 1, knocking US star Usher from the top spot to second position with his hit OMG, featuring Will.i.am.
Diana recently starred in the West End revival of The Rise And Fall Of Little Voice.
This Ain't A Love Song, by Scouting For Girls, last week's No 2, fell three places to five, in the chart compiled by The Official UK Charts Company.
There were two other new entries in the top 10, including Until You Were Gone by Chipmunk featuring Esmee Denters at No 3, and The Best by Tina Turner at nine.
The Best, which originally peaked at No 5 in 1989, has been supported by a Facebook campaign organised by Glasgow Rangers fans.
London rapper Professor Green fell three places to No 6 with I Need You Tonight. The track, which features Ed Drewett, samples the INXS hit Need You Tonight.
Another London rapper, Plan B, remained at No 4 with She Said, while US RnB star Kelis slipped two places to No 7 with Acapella.
Gives You Hell by the Glee Cast entered the chart at No 14 - one of seven new entries in the top 40.
In the album chart, the Iron Man 2 original soundtrack by veteran rockers AC/DC went in at No 1, squeezing Paul Weller's Wake Up The Nation, another new entry, into second place. Weller was ahead in the mid-week sales, but was overtaken at the weekend by AC/DC.
