Christian Foley may just have become the coolest teacher in the UK after being bigged up by 50 Cent.

A video of Christian, known as Just Muz or Muzzy Foley, rapping in lessons to pupils was shared on Facebook by the American artist to more than 37 million people who like his page.

Commenting on the shared post which the In Da Club singer captioned “He actually got some flow”, Christian wrote “Guilty as charged” and later added: “Amazing”.

The poet in residence at Cardinal Pole Catholic School in London is seen using his whiteboard marker as a mock microphone as he raps in the Hackney classroom about English and maths.

In the original video uploaded by Christian he described his occupation as “the greatest job in the world”.

Christian said he was shocked to see that a global rap star had seen his video.

He said: “My overwhelming feeling is surprise, what’s 50 Cent doing with his ear on the youth poetry scene of east London? How did he stumble on this?”

He joked at the nature of the rapper’s praise, and said he hoped it ultimately helps him help his pupils.

“I’m amused by the compliment, and its semi-patronising tone,” he said. “But yeah my main job is to help my students, and to focus on them, if 50′s praise creates opportunities for me, and therefore them, mission accomplished, if not – then it was just a cool Tuesday, and back to work.”
