The former Sugababes trio ran through the track for Reload Sessions, showing off some killer harmonies in the process.
The group are currently working towards their debut album, which is expected to be released in early 2014.
Lorde meanwhile is currently riding a wave of global success despite only being aged 16.
The New Zealand star saw her track 'Royals' hit No.1 in the US last week, making her the youngest singer to do so since Tiffany in 1987.
The tune is due to be released in the UK on October 20.
