This could be Kylie Jenner's smallest swimsuit to date.

The 18-year-old reality star enjoyed the warm California weather over the weekend by posing in a teeny, yellow bikini. Seriously, those are some skimpy bottoms.

Kylie wore another jaw-dropping swimsuit when she hit up the Coachella Music Festival in Indio, California. The Keeping Up With the Kardashians star, of course, posted a few pics of her sexy Louis Vuitton monokini.

Last year, Kylie admitted to ET that she barely has any regrets when it comes to what she posts on social media. "Only if I post the wrong selfie, then I am like 'ugh, that other selfie was so much better than that selfie,' but other than that I don't really regret anything," she said.
