Kanye West Mad at Kylie Jenner for Signing With Puma

Kanye West added more names to his enemy list, and this time it's a family member.

He is reportedly furious that sister-in-law, Kylie Jenner, just signed a contract with Puma. West knows the capacity of the youngest of the Kardashian-Jenner clan to influence in social media, and for her to endorse a brand other than Yeezy might cost him some sales.

The 38-year-old fashion designer took to Twitter on Feb. 9 to shut down reports that his wife Kim Kardashian's sister is going to seal the deal with PUMA.

"1000% there will never be a Kylie Puma anything. That’s on my family! 1000% Kylie is on Yeezy team!!!" he tweeted. But on Feb. 17, Kylie made it official by signing the contract with the company and this made West upset.

"She already signed. And I was mad for a little bit," he admitted to TMZ. "I'm really happy for her, though."

Although West seems to appear calm, HollywoodLife has learned exclusively that the family's matriarch, Kris Jenner, is worried that he's going to ruin her younger daughters' careers.

“Kris is starting to get nervous about Kanye and is putting him on lockdown from the other girls,” the source told the site. “She doesn’t want them too close to him right now because she is nervous he could affect their brand after the Puma debacle. She fears brands are becoming weary and doesn’t want his outbursts associated with Kendall and Kylie.”

Kylie has learned from her momager how to become a good businesswoman. The 18-year-old reality star wants to take any job opportunities that she is passionate about. She obviously didn't sign the contract to hurt West, but it was for her career growth.

“Kylie feels like business is business and signing with Puma has absolutely nothing to do with Kanye,” another HollywoodLife source said. “She’s actually really surprised he’s reacting the way he is. She’s disappointed because she thought of all people he would be proud of her for inking such a lucrative deal.”
