R&B superstar Mary J. Blige stunned revellers at a London nightclub by performing an impromptu set during a night out on Sunday (24Aug14).

The singer was partying at Boujis in London's West End with her husband Kendu Isaacs and a group of friends when she made her way into the Dj booth and grabbed the microphone to delight partygoers by performing a short set.

After the event, nightclub owner Carlo Carello posted a video of Blige singing from the booth on his Twitter.com page along with the caption, "Not every day does Mary J. Blige get on the mic... Great to have Mary J at Boujis Sunday @ Boujis (sic)."
