Kim Kardashian is not afraid to sing out her pettiness. In one of her latest Snapchat videos, Kim K is singing the controversial line about Taylor Swift from Kanye West's "Famous" while partying it up in Las Vegas last weekend.

The clip comes after the reality star exposed T. Swift for lying about authorizing 'Ye to rap about making her famous in his song. In the song, 'Ye raps: "I feel like me and Taylor might still have sex / Why? / I made that bitch famous." After it was released back in February, Swift appeared vexed and insulted about the line. Her camp later released a statement denying that "Kanye did not call for approval."

She went on to drive the point home during her acceptance speech at this year's Grammy Awards show. "There are going to be people along the way who will try to undercut your success, or take credit for your accomplishments or your fame, but if you just focus on the work and you don’t let those people sidetrack you, someday when you get where you’re going, you’ll look around and you will know that it was you and the people who love you who put you there, and that will be the greatest feeling in the world," she said.

But now, Kim K's video shows that Swift not only approved of the line—after 'Ye freestyled it for her -- but also agreed with the statement that he made her famous. Yikes. Now it seems that the Kardashian sister is rubbing it in her face.

The message? Don't come for the Kardashian crew because they keep all of the receipts.
