Plan B, aka Ben Drew, has opened up about his recent weight loss, revealing he went on a diet for himself.

"I had to lose the weight... I was a bit chunky, this is how I'm supposed to look," Ben said while promoting his directorial debut iLL Manors.

The multi platinum singer and rapper is known for being suited and booted on stage, but is now going for a more casual look.

He said: "For the last 3 years, I've been wearing clothes I wouldn't normally wear, for a purpose, and now I'm a director I can dress like this... This is how I look when I'm chilling."

iLL Manors is released on June 6 and is already getting rave reviews from critics.
