The supermodel, who turned 22 Friday, celebrated the occasion in a cropped ribbed tank and baggy ripped jeans, plus some massive sparkling hoops. To dress the look up a bit, Jenner slipped on her $10,000 Saint Laurent knee-high boots — already a celebrity favorite, worn by Celine Dion, Kim Zolciak-Biermann and Rihanna. The crystal-embroidered chunky-heeled footwear, which debuted on Saint Laurent’s AW17 catwalk, made it clear that Jenner was the center of attention as they sparkled in the paparazzi camera flashes.

Clippers star, 28, also kept things casual in a pair of ripped jeans, tan Chukka boots, a grey shirt, and a blue and white checkered flannel. He and Jenner’s courtship has been heating up in recent weeks. In October, the stars stepped out for a special double date with Jenner’s sister, Kylie, and her rapper boyfriend Travis Scott at Universal Studios’ Halloween Horror Nights in Hollywood. She was also seen cheering him on at a Clippers/Lakers game Oct. 19, and hanging with him at a Halloween party earlier this week. Splash News “She thinks he’s dorky and funny, but also cool and sexy — he has a certain attractive ‘swagger,’ ” an insider said of the pair. “They are seeing each other more, and Blake is doing everything in his power to make Kendall his girlfriend.” “She’s always working and traveling and knows a full-blown relationship isn’t necessarily the best idea, but things are heating up,” the source added. “She is for sure enjoying dating him.” Jenner was previously linked to rapper A$AP Rocky. Griffin shares two children with his former girlfriend Brynn Cameron, a former basketball player at the University of Southern California. Cameron and Griffin reportedly split over the summer.

The couple — who are expecting a baby girl (their third child) via surrogate early next year — were photographed walking alongside one another as they entered the restaurant. Kardashian West, 37, wore a blue bra top, high-waisted gray skin-tight skirt with ankle-strap sandals. West, 40, wore the quintessential Yeezy get-up: a baggy brown shirt, dark sweatpants, shearling coat and sneakers worn with extra high socks. And both sported jewelry from his collaboration with Jacob the Jeweler.
