Kim Kardashian is baring all of her curves on vacation.

The stunning reality star soaked up the sunshine in Mexico today, and even shared a very revealing photo of her relaxation time. In the pic, the brunette is lounging with her booty on display in a tiny yellow bikini. And no bathing suit top for her, thanks! She’s not about those tan lines.

Lying on the reclining chair next to her is Kim’s friend Joe Frances’ pregnant girlfriend Abbey Wilson, showing off her own round curve — her belly!

Kim captioned the photo: “#OurLovelyLadyLumps.”

We have to wonder if Kim was offering any pregnancy advice to Abbey. Her own experience being pregnant with 1-year-old North West has taught her a lot, after all, including the unforgettable words of wisdom to “never leave the house.”

We hope you’re taking notes, Abbey!
