Kendall Jenner may be making "good boob day" a thing.

The reality star took to her website on Wednesday to explain that racy pizza-emoji braless torso/sheer top pic she shared to Instagram last November.

"I don't know if you can relate, but I just felt like I was having a really good boob day, lol," the 21-year-old wrote. "Do you know what I mean? Your boobs go through phases and on this particular day, I felt like they just looked nice!"

"My shirt was see-through, so I took this photo and just texted it to Hailey [Baldwin] and Gigi [Hadid] before I left to meet them and was like, 'Is this too much?'" she continued. "They wrote back, 'It's kind of a lot, but if you're into it, go for it!'"

Good to know it was a friend-sourced pic, but that still doesn't explain the food emojis!

"As far as the pizza emojis go, when I decided to Instagram the picture, I could've covered my nipples with anything, but I chose them as a little nod to Pizza Boys (the DJ/friend group I'm part of)," Jenner explained.

Of course, the Keeping Up With the Kardashians star has nothing to explain, especially because the sheer, nipple-baring look has become a staple of her style.

Jenner shared an NSFW modeling snap to Instagram on Wednesday of herself in a sheer bra posing on a dusty car with the message, "Boys Lie."

Speaking of boys, Jenner's been spotted out with A$AP Rocky quite a bit lately, sparking rumors that the pair are kinda becoming a thing!
