Kardashian cleavage alert! Kardashian cleavage alert!
This is actually our second Kardashian cleavage alert of the day, considering Kim Kardashian celebrated an Instagram milestone over the weekend by sharing a massive cleavage photo.
And now Kim is joined by sister Kourtney for a seemingly random reveal of their large boobs.
"Just a chill sister Saturday," Kourtney wrote as a caption to the photo above, which features the siblings wearing purple lipstick, sleek black outfits and very low-cut tops.
It's unclear why the Kardashians were so dressed up (or dressed down, depending on your viewpoint)... but do they really need a reason?
Heck, Kourtney may have just been giving Scott Disick a look at what he's been missing these days. She's been doing that a lot lately.
Both sisters, meanwhile, attended an 18th birthday party for Kylie Jenner over the weekend, but we know they didn't dress this way for it.
That's because Kim posted the first-ever selfie of both Kris and Caitlyn Jenner at the event.
