The reunited Sugababes cover the teen sensation and perform a new song.

Mutya Keisha Siobhan stopped by the Reload Sessions studio to perform two acoustic songs: a cover of the chart-topping ‘Royals’, by 16-year-old singer-songwriter Lorde, and their own ballad, ‘No Regrets’.

Watch both clips below; the trio certainly seem warmed up for their upcoming UK tour. The group recently released a video for the summery ‘Flatline’, and their debut album as MKS is expected early next year. For more Mutya Keisha Siobhan, check out Chal Ravens’ review of their first-ever live show.
