"I am so proud of my beautiful wife Kim Kardashian West for officially becoming a billionaire," Kanye wrote on Twitter.

"You’ve weathered the craziest storms and now God is shining on you and our family. So blessed this is still life. So I made you this still life. We love you so much."

Kanye's tweet comes after his wife sold 20 percent of her KKW Beauty company to beauty giant COTY for $200 million.

The deal announced on Monday values KKW Beauty at $1 billion, making Kardashian West worth about $900 million, according to Forbes’ estimates.
