The 'Sorry' hitmaker splashed out on a lavish gift for the rapper when he turned 31 in November, but according to TMZ, he wanted to show his gratitude for a recording session they took part in with Mariah Carey and T.I. back in July.

Despite Justin's generous gift, it seems French wasn't entirely happy with the piece of jewellery as he recently splashed out another $90,000 on diamonds for the chain.

The 21-year-old singer is happy to splash the cash, on both his friends and himself and recently revealed he will have a number of different buses on his 'Purpose' world tour.

He said: "I will be touring on a bus. It's a different vibe, I don't mind it. I have a studio bus and a workout bus, it's just a big gym.

And Justin - who is a massive skating fanatic - will also have a half pipe with him in case he gets the urge to ride.

He added: "I'm bringing a half pipe on tour."

The handsome star was also asked, if his tour rider was leaked, what the most bizarre thing on it would be and he revealed his weakness for cheese crackers with peanut butter.

He said: "I like Ritz crackers with peanut butter."
