Kylie Jenner, Kendall, & Hailey Baldwin Flaunt Tattoos, Bikinis, Butts With Jaden Smith: Kylie Debuts R-Rated Song

Kylie Jenner, Kendall Jenner, and Hailey Baldwin are ready to sizzle this summer. The Keeping Up with the Kardashians (KUWTK) stars joined Hailey and some other friends to flaunt their bikini bodies and butts at a Memorial Day pool party, reported Us Weekly.

But it was Kylie and Baldwin who dared to compare their thigh-high tattoos. The pals posed to flaunt their fannies and swing their hips while exposing the tattoos.

While the bikinis didn’t quite match, the body art did, and so did their curves. Jenner, 18, got her tattoo in December. It displays a phonetic spelling of the word “sanity.” But she waited until it was warmer weather to display it in that sizzling black bikini, with the straps styled to show off her tattoo.

Hailey, 19, copied the choice of which body part should display her body art. However, her tattoo spells out “gente” (Portuguese for “people”). Baldwin went for a variety of colors in her bikini.

In addition to that tattoo showdown, the two posed with other members of their girl squad, displaying that they’ve achieved those essential friendship goals. Kendall and model Cami Morrone were also ready to do justice to the perfect weather for their Memorial Day celebration in the form of a bikini pool party.

“Girls girls girls,” summed up Jenner for her caption.

And in a demonstration of just how close the friends have become, Morrone showed off her posing and modeling skills with a photo that compared their perfect posteriors.

But it wasn’t just girls. Joining Jenner’s closest friends was her ex-boyfriend Jaden Smith, according to OK! magazine.

Helping to keep it real, big sister Khloe Kardashian decided to join the pool party. Khloe offered up her choice of how to entertain the crowd by twerking wildly for the camera, all captured for Snapchat.

But the pool party isn’t the first time that Jaden has been spotted again with the KUWTK star. Jenner recently enjoyed a night on the town with both Scott Disick (the former boyfriend of her sister Kourtney Kardashian) and Jaden, according to Hollywood Life.

The 18-year-old and Scott attended Nylon x BCBGeneration Young Hollywood Party, but soon after they entered, they were joined by Jaden. Smith danced with Kylie, and Amber Rose visited with them as well.

While Jenner is making it clear she knows how to enjoy herself, she isn’t neglecting her entrepreneurial drive. She and Kendall are teaming up to write another book, according to Cosmopolitan.

In 2014, the sisters wrote a young adult novel, Rebels: City of Indra: The Story of Lex and Livia. Publisher Regan Arts revealed that the new book, Time of the Twins, debuts on November 15.

“Time of the Twins follows the story of Lex, a rebellious orphan, and her twin sister, Livia, a pampered heiress, as they make a grueling journey in search of the mother they thought was dead. They will have to face an ancient prophecy that calls them the long-awaited ‘twin saviors,’ destined to save their city of Indra and all of its people.”

The KUWTK stars will get help from their co-authors, Elizabeth Killmond-Roman and Katherine Killmond, as they tell the tale of how Lex and Livia learn more about each other and the fate that awaits them.

In addition to the book, the sisters have their own fashion line together, and the most youthful member of the Keeping Up with the Kardashians family (not counting the various offspring of her older sisters) also boasts her own cosmetics line.

What’s next? The debut of an R-rated version of Mister Rogers’ Neighborhood theme song, according to Billboard.

Burberry Perry uploaded the “Beautiful Day” track to SoundCloud from his own six-track EP. In it, Jenner does a rap-talk version (rated R) of the familiar theme song.

And as happens when you’re the youngest of a family that contains Kim Kardashian, it’s already being compared to Kim’s.
