The rapper, who actually turned 21 on Saturday, celebrated at Jalouse nightclub in London and was joined by a bunch of celebs and the cast of The Only Way Is Essex! Random.
Chip Diddy Chip turned up suited and booted in a black and white outfit and sunglasses and seemed to have had the time of his life, getting all emotional on Twitter afterwards:
Other stars that appeared at the bash included JLS, Jade Jones from boy band Damage, Krept & Konan, Skepta, Talay Riley and even American superstar Diddy gave the 21-year-old a birthday Twitter shout out.
Looks like it was a great party. We’re expecting an invite next year!
