On Sunday night, the Keeping Up With the Kardashians ten-year anniversary special aired on the E! network.

It was a time to reflect on how far the first family of reality television had come, as well as to ponder the qualities that have made them such an irresistible draw to so many millions of Americans:

There’s Kris Jenner’s talent for marketing, the sisters’ impressive social media prowess, that one-of-a-kind family dynamic, and of course, their butts.

Obviously, Kim has the most famous backside of them all, but her sisters are no slouches in the ‘donk department.

We don’t want to get into a debate over whose butt is the best, because that’s like choosing your favorite Beatle.

There’s something for everyone, and there’s no wrong answer, unless you say something crazy, like “Ringo” or “Khloe’s.”

(Sorry, but they’re both too fake for our taste. Ringo’s not even his real name!)

That said, we think anyone creepy enough to compose an actual list would put Kourtney’s ass in one of the top spots.

But that doesn’t mean there isn’t room for improvement.

According to Radar Online, Kourt has already scheduled a butt lift procedure for sometime in the very near future.

That might seem strange, as Kourtney’s bikini photos never disappoint, and she seems to pride herself on being one of the least “enhanced” Kardashians.

But apparently, at 38 and after three kids, Kourt feels it’s time for a little preemptive maintenance work.

“Kourtney is sticking religiously to the ‘body plan,’ and according to her calendar, it’s time for a butt life,” says one insider.

Take a moment to pause and imagine an actual wall calendar with “BUTT LIFT!!!” written in red marker on today’s date.

That’s funny stuff.

Anyway, it seems it was always Kourt’s plan to have work done before she starts noticing signs of age.

“Kourtney doesn’t want to patch herself up as she goes, like other Hollywood stars,” says the source.

And because she’s a Kardashian, it stands to reason that Kourtney is addressing the problem butt-first:

“Her butt is her pride and joy,” says the insider.

“She’s worked hard to keep it natural, but now it’s time for a little surgical help.”

Hey, with how big of a role butts have played in her family’s empire, we can’t blame her.

Plus, it might help make Scott Disick jealous, and that’s always a bonus.
