"For Mother's Day, he's like the cutest," Kim gushes. "So, a brand offered me a million [dollars] to do a post and they... typically knock off Yeezy. So, I said, 'You know what, it's great money. Let me ask Kanye how he feels about it.'"
"He's like, 'No babe, I really don't want you to do that,'" Kim, 37, continues. "Understandable but that's a lot of money."
Two weeks later, for Mother's Day, Kanye sent Kim flowers and an envelope because he was out of town recording new music.
"So, I open the envelope and it's a million dollar check," Kim reveals. "And there was a note, saying, 'Thank you for always supporting me and not posting.'"
That wasn't the end of the presents though! "In the rest of the envelope, there was a contract to be an owner of Yeezy -- to have my percentage," Kim says. "That was my Mother's Day present."
Though she "did feel bad" about cashing the check, when her mom, Kris Jenner, asked if she planned to, the answer was instantaneous. "I was like, 'You better believe I'm gonna cash this,'" she recalls.
A source told ET that Kim and Kourtney Kardashian, along with their children, were all present during 41-year-old Kanye's speech. The source also noted that Kim just stared at Kanye -- who recently announced that he's changing his name to Ye -- and didn’t seem fazed by his remarks, despite him receiving audible boos from the crowd.
