S Club 7 have shot straight in at number one with Have You Ever.
They knocked Blue from their perch at the top of the charts even though they'd only been there a week with If You Come Back To Me.
And as predicted, Kylie Minogue's sister Danii went in at number three with Who Do You Love Now? as Kylie slips slowly down the charts with Can't Get You Out Of My Head.
It's a bit of a comeback for Danii: it's her first single for three years.
It was a good week for U2 and DJ Otzi, too.
U2 scored the highest new entry at five with Walk On and DJ Otzi went in at nine with Do Wah Diddy just two places above his Hey Baby which has been around for a while.
And as predicted, Robbie Williams' new album Swing When You're Winning went straight in at number one in the album charts.
