Kylie Jenner's hips don't lie!

The 18-year-old reality star flaunted her curves in a Chanel swimsuit by the pool and showed off her hip tattoo in a new photo on her Instagram.

The red ink on her hip reads, "Sanity" spelled out phonetically.

Kylie rarely shows this one off, but she has given us a closer look on her Instagram.

When she initially got the tattoo in December 2015, she credited Bang Bang Tattoo in New York and wrote, "All red" on the photo's caption.

All red. @bangbangnyc

Just a couple of weeks ago, Kylie showed off her most recent ink.

The tattoo reads "Mary Jo" for Mary Jo Campbell -- Kylie's maternal grandmother.

"Grandmothers name in my grandfathers handwriting," she wrote alongside the snap.

While Kylie's seeing red ink on her body, it's hard to get her red lip kit!

She managed to sell out of her signature lip kits this morning, again.

Another restock is supposed to happen in a week, but it's not lip kids that Kylie is profiting on.

Two new photos were released for Kylie's $1 million PUMA campaign on March 13.

PUMA shared this photo of Kylie with a basketball in their blue sports bra, matching patterned running capris and black sneakers.

Kylie also shared a photo from her fierce campaign.

"Excited to reveal my campaign for the @PUMA Fierce, a lightweight trainer with zero excuses, available starting 4/1 on PUMA.com, PUMA retail stores, and select retailers worldwide," the caption reads. "The next level starts here #ForeverFierce."

Even though her brother-in-law Kanye West has a deal with Adidas and tweeted, "1000% there will never be a Kylie Puma anything. That's on my family! 1000% Kylie is on Yeezy team!!!," Kylie did not back away from Puma.

"Kylie represents a fresh and exciting new era for fashion," Puma said in its statement, "and we couldn't think of a more fitting and influential female to headline this campaign for PUMA."

Sorry, Yeezy!
