The two runway stars took a stroll through the streets of Los Angeles on Wednesday, a day before the rumors of romance troubles began to swirl, where Hadid appeared to be in good spirits as the besties laughed and chatted all afternoon.
The pair hung out again on Thursday, and they appeared to be in a noticeably more dour mood. The friends were spotting leaving the French bistro Zinque, in West Hollywood.
Jenner and Hadid look as effortlessly stylish as always, with the 20-year-old Keeping Up With the Kardashians star rocking a low-cut black crop top under a white Matador-style jacket along with high-waisted jeans.
Hadid flaunted her toned midriff in a vintage-style black and silver mod halter top and faded, black skinny jeans.
Later, Hadid hopped on Instagram to share a black-and-white selfie she snapped with Jenner, which she captioned simply, "DTLA."
Hadid's decision to go with a greyscale pic may have something to do with the desaturated snapshot Malik shared to Instagram hours earlier. The former One Direction star posted a shirtless pic of himself on a balcony, with his back turned to the camera, raising a drink to the sky. The 23-year-old "Pillowtalk" singer chose to forgo a caption altogether.
ET reached out to Hadid and Malik’s reps for comment on the reported split. Malik’s rep had no comment.
Hadid, was previously in a relationship with singer Cody Simpson until they split in May 2015. She was first linked with Malik six months later when they were spotted on a date in Los Angeles in November -- three months after Malik called off his engagement with Little Mix singer Perrie Edwards.
