Last year's X Factor champion Alexandra Burke has beaten pop icon Robbie Williams to the top of the UK single charts after both performed on the show last weekend.
'Bad Boys', which features contributions from US rapper Flo Rida, sold more than twice as many copies (185,000) as Robbie's comeback single 'Bodies', which trailed behind at No 2.
The two new entries pushed last week's No 1, 'Oopsy Daisy' by Chipmunk to No 3.
Alexandra's debut, a cover of Leonard Cohen's 'Hallelujah', was the best-selling single of 2008. So far 'Bad Boys' is the fastest-selling single of 2009.
'Bodies' marks Robbie Williams' 20th top five single of his 13-year solo career - six of which took the top spot.
Burke said: "I'm blown away... I've been recording my album for the last six months, so I'm hugely excited to finally be sharing my music with everyone.
"I want to say a big thank you for all the support I'm receiving, I'm one very happy girl today."
Meanwhile, British rock band Editors topped the album chart with 'In This Light and On This Evening'. Chipmunk's 'I Am Chipmunk' entered in second place, pushing Madonna's greatest hits compilation 'Celebration' to No 3.
Shakira's 'She Wolf' album was a new entry, jumping straight to No 4. Paolo Nutini's 'Sunny Side Up' saw a resurgence of popularity, leaping from No 31 to No 5.
