Mary J. Blige decided to give one of her fans the ultimate surprise recently, as she flew into London especially to meet one of her most dedicated supporters!

The Queen of R&B teamed up with MasterCard to treat Rana Otemro to an evening she will never forget, as she thought she was there to watch a live-streamed performance of her idol from New York.

Only Rana soon realised that Mary was performing live in front of her, as a screen was dropped to reveal her stood on stage, much to her friends and families surprise!

Clearly stunned as to what happened, Rana said: “The best moment of my life. Mary J Blige is my icon – her music is so honest and real. When she appeared in front of my eyes, I had to turn around and check that my friends were seeing the same thing as me - I really couldn’t believe it."

While Mary was happy to make a fan's dream come true: “My fans inspire me to make music, they are the reason I do what I do."

Hey Taylor Swift, any chance you want to surprise us with something similar? We would die.
