Kendall & Khloé Skip Kylie Jenner's Birthday Festivities in Italy

Their sister Kylie Jenner is cruising around the Amalfi Coast in a massive yacht this week for her birthday celebrations, but all her sisters won't be joining.

Back in Hollywood, Kendall Jenner and Khloé Kardashian where seen showing off their stunning looks while exiting The Nice Guy Friday night in L.A.

The 23-year-old supermodel showed off her toned figure in a tight neon green dress along with a pair of pointed heels.

Adding to the fashion icon's look, Kendall carried her belongings in a glittering silver fringed handbag.

Her brunette hair was pulled back into a tight pony and her stunning features were enhanced with matching green eyeshadow.

35-year-old Khloé looked absolutely gorgeous as she showed off her slender figure in a pair of skintight black leather pants.

The "Keeping Up With The Kardashians" star teamed the skintight number with a clingy black plunging vest top and white heels while accenting the look with a hot pink pedicure.

The famous sisters were also joined by good pals Justin Bieber and his wife Hailey Bieber at the Hollywood hotspot.

Hailey looked smoking hot while wearing a pink crop top and jeans, complete with tousled locks.

Justin opted for a trendy display in his smiley-face dip-dye "Drew" hoodie and baggy jeans.

Kendall and Khloe's sister Kylie has been living her best life in Italy celebrating her 22nd birthday while on board a massive yacht.

The brunette bombshell has also been joined on the trip by her daughter Stormi, one, baby daddy Travis Scott, Kourtney Kardashian's ex Scott Disick and his girlfriend Sofia Richie.
