The outspoken rapper recently made it clear he was not amused by rumours suggesting 18-year-old Kylie would be signing a $1 million (£700,000) contract with Puma, especially as she had been such a big fan of his Yeezy sneaker brand with Adidas.

"1000% there will never be a Kylie Puma anything," he raged on Twitter as he blasted the reports on 9 February (16). "That's on my family! 1000% Kylie is on Yeezy team (sic)!!!, Puma we gone give you your measly million dollars back!!! Never try to divide the family!!!"

Kylie remained quiet about the claims as she joined her family to support Kanye at New York's Madison Square Garden last week (11Feb16), when he unveiled his Yeezy Season 3 clothing designs for the German label, but on Wednesday (17Feb16), it was revealed she had indeed taken the cash to promote Puma.

"I am pleased and excited to be able to confirm that PUMA is indeed working with Kylie Jenner," Adam Petrick, Global Director of Brand and Marketing for Puma, said in a statement. "Kylie will be featured in the brand's Spring/Summer women's training campaign launching in April 2016.

"Kylie represents a fresh and exciting new era for fashion and we couldn't think of a more fitting and influential female to headline this campaign for Puma."

Now Kanye, who is married to the teen's sister Kim Kardashian, has admitted he was initially angered by the news as he had no idea Kylie had even been in talks with Puma.

"She had already signed," Kanye explained to TMZ.com, "and I was mad for a bit."

However, he adds, "I'm really happy for her though."

Kylie has yet to remark on her latest business venture, or her brother-in-law's comments.
