Florence + The Machine covered Justin Bieber's 'Where Are U Now' in the Radio 1 Live Lounge on September 29 afternoon, Gigwise reports.

The singer paid an extra-long visit to the BBC Radio 1 studios, during which she performed several tracks from her latest album, How Big, How Blue, How Beautiful, as well as her Calvin Harris collaboration 'Sweet Nothing'.

After she'd sung the likes of 'Ship To Wreck', 'What Kind Of Man', 'Queen Of Peace' and 'Delilah', she then turned her attention to Justin Bieber's contribution to Skrillex and Diplo's Jack U project - 'Where Are U Now'.

The cover is likely to split opinion - just as Florence's version of Beyonce's 'Halo' did when she was last in the Live Lounge a few years back.

Florence + The Machine played several sold-out shows at Alexandra Palace last week.
