Remember the rapper Plan B? Best known for his songs 'Ill Manors' and 'She Said'? Yeah, him.

Well, he made a comeback at a gig in London last night (24 July) – but no one recognised him.

Five years after disappearing from the spotlight to focus on fatherhood, the rapper – real name Ben Drew – appeared at Shakespeare's Globe for a one-off concert, revealing his dramatic weight loss and new silver hairdo.

Eagle-eyed fans were quick to notice how different he looks, and took to social media to comment on his new image.

"Who are you? And what have you done with Plan B?" one person wrote, while someone else joked: "Who've you come as? Draco Malfoy?"

Another added: "Plan B has lost so much weight!"

Back in 2010, Plan B told The Sun that he had been encouraged to lose weight by Ray Winstone when they worked on The Sweeney together.

"We were talking about my character and how someone as young as me has got the part," he said.

"We were saying how I've got to be a man in his early thirties, super-smart, excels in exams, brilliant at sports and Ray looked me up and down and goes, 'Are you sure you're going to get yourself in good enough shape?'

"I thought right then and there, 'I'm going to do it'. That's the extra incentive I needed. I thought, 'I'll f**king show you, pal'."
