The 23-year-old model shared a picture with Malik in bed Tuesday on Instagram Stories after appearing to reconcile with the 25-year-old singer.
The snapshot shows Hadid lying in Malik's arms as he plays a Pokemon game on a tablet. The model attended the New York premiere of Ocean's 8 earlier in the night.
"after party like," she captioned the post. "Making it rain Pokemon cards."
Hadid and Malik fueled reconciliation rumors in April after they were spotted kissing during an outing in New York. The pair had announced their split in March after two years of dating.
"I'm forever grateful for the love, time, and life lessons that Z and I shared," Hadid said at the time. "As for the future, whatever's meant to be will always be."
"Gigi and I had an incredible meaningful, loving and fun relationship and I have a huge amount of respect and adoration for Gigi as a woman and a friend," Malik added. "She has such an incredible soul."
