The photogenic couple cozied up on the rooftop of Milk Studios and were “sitting very close together and kissing each other” throughout the night, an eyewitness tells Us.
“They looked very happy and were all over each other,” the insider added.
Malik, 23, wore a black leather painted jacket for the celebration, while Hadid, 20, donned a two-piece maroon outfit and oversize sunglasses.
Earlier in the night, the former One Direction band member gave a rousing performance to a small group of about 200 fans at the iHeart Radio Theater, belting through hits like “Pillowtalk,” “Like I Would” and “It’s You.”
“A lot of people have been on this stage and no one has blessed it like you just did,” the show host said afterward. “What is it like to receive support from your fans?”
Malik then looked out at the screaming crowd and said, “It’s so amazing. At the end of the day, it all comes down to them.”
Supermodel Hadid watched the entire performance on a monitor backstage.
The pair first began dating toward the end of November, shortly after Hadid split from Joe Jonas (Malik was previously engaged to Little Mix’s Perrie Edwards.)
“Was it cool to have your girlfriend in the video?” Zach Sang & the Gang radio host Jill asked the singer, referring to Hadid’s cameo in “Pillowtalk.”
“Yeah, that was cool It was something different,” he responded. “We enjoyed it, it was fun. Had a lot of fun on set.”
On Wednesday, Hadid posted a stunning shot of Malik to Twitter with the simple caption "I mean.…" and immediately received backlash from haters.
In response, Hadid kept her retort simple: “I’ve dated 3 guys in 3 yrs, hun. My walk can always get better; I hope the unrelated bitterness in ur heart can too."
