A fortnight ago, her album The Fame went back to the top of the chart for a third time.
Scouting For Girls' eponymous debut album, which spawned hits including She's So Lovely and Elvis Ain't Dead, went to number one in 2008 after 18 weeks in the chart.
That album re-entered this week's album chart at number 35.
Six albums were new entries including Craig David's collection of covers, Signed, Sealed, Delivered, at number 13, and Madonna's Sticky & Sweet Tour live album at 17.
