One person who does not appear to agree with Kanye West's business acumen is his sister-in-law Kylie Jenner, who has decided to go ahead with her Puma deal despite his protests that it would 'divide the family'. Calm down Kanye, it's just a pair of sneakers.

Kylie JennerKylie Jenner says yes to Puma

The 18-year-old Kardashian sister has been working really hard over the last year with her business ventures, becoming an ambassador for Nip + Fab, launching the clothing line Kendall + Kylie with Topshop, unveiling her sell-out Lip Kit and also starting her own mobile app like big sister Kim. Now, she's set to make an even bigger success of herself in a lucrative new deal with Puma, but her brother in law and Adidas endorser is really, really, REALLY not happy about it.

'Puma we gone give you your measly million dollars back!!! Never try to divide the family!!!' West ranted on Twitter on February 9th 2016. '1000% there will never be a Kylie Puma anything. That's on my family! 1000% Kylie is on Yeezy team!!!'

No wonder Kylie tried to be secretive about the whole thing. Now the media is reporting that West was super angry that she's gone against his, for want of a better word, 'advice', even though he claimed to have hit out AFTER learning that Kylie had already made arrangements on signing the deal.

'She had already signed and I was mad for a little bit, but I'm really happy for her though', he told reporters in footage obtained by TMZ. 'The only company that ever supported me was Adidas'.

Puma's Global Director Adam Petrick announced that the deal had been made yesterday. 'I am pleased and excited to be able to confirm that PUMA is indeed working with Kylie Jenner', he said. '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.'
