Charli XCX covered Taylor Swift's 'Shake It Off' in the Radio 1 Live Lounge this afternoon (10 February).
The singer had just flown into England from LA, where she performed at the Grammys after-party, and sounded a little sleep-deprived during her short chat with the show's host Fearne Cotton.
She didn't let it affect her performance though - after an acoustic rendition of her Rita Ora collaboration 'Doing It', she launched into an energetic, pop-punk style cover of Taylor Swift's 'Shake It Off'.
Rather than going down the traditional Live Lounge route of performing a slower, more melancholy version of an up-tempo number, the singer decided instead to speed the song up considerably.
