On Thursday Kanye West premiered his new album, The Life of Pablo, during a sold-out Yeezy Season 3 show at Madison Square Garden. Anticipation for the album had been building ever since (and probably even before) its name was changed like 27 times, and Kanye built up the hype even more when he tweeted the album cover just before the show.

Just after the show, however, Kanye tweeted a different album cover, this one featuring an ass that many at first believed was Kim Kardashian's.

But, as the Daily Mail reports, the mysterious derriere doesn't belong to Kim at all. It's the ass of swimsuit model Sheniz Halil, who posted the photo that appears on the cover to Instagram just a few weeks ago. One might think Kim would be hurt by her husband using a different butt on his album cover (she is the ass queen, after all), but it turns out she not only endorsed the move—she handpicked the booty. "As they say, do what you know," a source told TMZ. "And Kim knows ass." Apparently Kanye gave her several pictures to choose from, and she thought Halil's ass was the best.

How does Halil feel about her butt's new notoriety? "I'm flattered one of most influential and talented artistes [sic], not to mention married to ultimate queen bootay, used my pic," she wrote in an Instagram post. "Don't know how or why, but I'm flattered." When Queen Bootay herself threw her a like, she freaked out even more. "I jus [sic] let died omg Kim Kardashian liked my picture thank you," she wrote. Safe to say Halil's ass is now the world's second-best.
