Pop act Sugababes are on course to top both the singles and album charts this weekend, early sales figures indicate.
The group are the most successful UK female act of the 21st Century
Change, the girl group's first album with new singer Amelle Berrabah, is currently outselling close rivals Jack Penate and Bruce Springsteen.
Lead single About You Now looks likely to stay at number one for a third week, beating the likes of Elvis Presley.
Meanwhile, Big Brother twins Sam and Amanda are only just scraping into the top 40 with their debut release.
Their cover of Aqua's Barbie Girl is currently resting outside the top 30, alongside the comeback single by fellow reality TV contestant Chico, according to figures published in industry journal Music Week.
New entries are expected for quirky pop-rock band The Hoosiers and Depeche Mode frontman Dave Gahan.
But a campaign to get the Sex Pistols' God Save The Queen to number one 30 years after it was first released appears to be destined for failure.
Early sales figures have the record at number 28.
Last year, Sugababes were named the UK's most successful all-female group of the 21st Century, having scored 16 hit singles since 2000.
Since then, they have topped the chart twice - with Comic Relief single Walk This Way and their current release.
Pop stars Girls Aloud are close behind, with 16 top 10 hits to their name.
