The decision to move from “Hallelujah” to “Bad Boys” has paid off for Alexandra Burke. Burke beat Robbie Williams on this week’s UK Singles chart, landing the no.1 spot with “Bad Boys”. Taken from her debut album, Burke’s “Bad Boys” came in strong on this week’s chart thanks to 185,000 copies of the single being moved. Featuring Flo Rida, “Bad Boys”‘ is the fastest selling single of 2009 according to BBC. “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,” Burke says of the success. Burke’s debut album, post winning the X-Factor title, was released today (Monday, October 19).
