US pop singer Pink has retained the UK number one spot for the second week in a row.
Her latest single So What hit number one last week - her first chart-topped in six years - after a much-hyped battle for top spot with Oasis failed to materialise.
And the 28-year-old, born Alecia Moore, has remained at the top of the British charts for a second week.
Sugababes entered at number three with their new single Girls while the Kaiser Chiefs debuted at five with Never Miss A Beat.
Oasis' new album Dig Out Your Soul, their seventh, reached the top spot in the album charts, with Kings Of Leon and Will Young each falling one place.
The top ten tracks in the UK singles chart are:
1 Pink: So What
2 Kings of Leon: Sex On Fire
3 Sugababes: Girls
4 Rihanna: Disturbia
5 Kaiser Chiefs: Never Miss A Beat
6 Ne-Yo: Miss Independent
7 Katy Perry: I Kissed A Girl
8 Pussycat Dolls: When I Grow Up
9 Gym Class Heroes: Cookie Jar feat. The Dream
10 Iglu & Hartly: In This City
