The multi-millionaire rapper took to his Instagram stories where he shared videos from the birthday surprise in honour of his mother.

Diddy's son, Justin was the first to gift his grandma with a diamond necklace with her moniker “Mimi” on it.

This was followed by Diddy's $1M cheque.

It didn't end there as he went on to surprise his mum with a Bentley. 

“I can’t believe this,” a shocked Janice said.

“A very important add-on to the gift: a driver comes with it. You ain’t gotta worry about it. You can just tell him your destination. It’s your favorite color,” Diddy said.
