Yeezy's got back!

Kanye West grabbed lunch with a pal in Calabasas over the weekend, and we couldn't help but notice his butt! He's turning into a Kardashian right before our very eyes! To be fair, he was wearing baggy sweats and a hoodie, but it appears he's put on some serious weight during his time out of the spotlight following his mental breakdown last October.

'Ye kept quiet on Kylie Jenner's pregnancy news, but he could be partially responsible for it. How, you ask? Apparently, Yeezus has been close with the LipKit queen's baby daddy Travis Scott for years, and the "Goosebumps" rapper even considered him family before they actually became one.

"He took me in super early in my career. He’s like my stepdad. We always had that relationship where we cook up ideas. We [talk] all the time about random s—: life and how we can do better as people and as rock stars. Our goal is to help people figure out who they want to be," he told Complex back in 2015.

It sounds like the Texas-born hip hop star couldn't be more thrilled to start a family with the youngest KarJenner.

“He was so excited he couldn’t keep it in. He’s been so affectionate and protective of Kylie since they found out. He can’t wait to be a dad," a source dished to People.

We wonder if the Louis Vuitton Don will drop Tyga from his label now that he's been replaced by Travis?!
