Duffy has made it to number one on both the singles and album charts this week as her debut album 'Rockferry' crashed into the top spot.
The album outsold the rest of this week's top ten by shifting 180,000 copies, the Official Charts Company have revealed, pushing Amy Winehouse's 'Back To Black' down to no. 2.
Duffy's single 'Mercy' also managed another big week of sales to take a third straight week at No. 1, ahead of H Two O's 'What's It Gonna Be' ft. Platinum, and Nickelback's 'Rockstar' at three.
The rest of the top five featured Onerepublic's 'Stop and Stare' and UK soul singer Taio Cruz's 'Come On Girl', while Alphabeat, Flo Rida and Westlife all moved up into this week's top ten.
