Gigi Hadid and Zayn Malik are adding some extra fuel to those romance rumors!
The model and the former One Direction singer originally sparked speculation when they were photographed leaving a party together after the American Music Awards on Sunday, and now they've been spotted out and about yet again.
An eyewitness exclusively tells E! News the duo enjoyed dinner together at The Nice Guy in Los Angeles on Tuesday night with Gigi's sister, Bella Hadid, and simply couldn't get enough of one another.
"Gigi and Zayn couldn't keep their hands off each other," the source reveals. "They were holding hands under the table, whispering in each others' ears, and Zayn [was] holding Gigi's leg. Gigi was so attached to him that she even followed Zayn outside to the patio during a smoke break."
A second insider adds, "Gigi and Zayn sat next to each other and looked like a couple, laughing having a good time."
Though the eyewitness says the pair "seemed close and comfortable in each other's company," it may be too soon to call them an official couple just yet.
Another source recently told us, "They are just friends and are casually hanging out. She is not looking to jump into another relationship so soon. Gigi is a relationship-type kinda girl, but she wants to just have some fun and take time for herself and her career at the moment."
In fact, Gigi broke up with ex-boyfriend Joe Jonas less than a month ago due to their differing work schedules. Luckily, there was no bad blood between them after the split.
"They still remain friends but their schedules started affecting their relationship," another source said of the amicable exes.
Malik, on the other hand, ended his highly publicized engagement to Perrie Edwards in August. Talking to Fader magazine he denied breaking up with her via text message. "If you could word it exactly this way, I'd be very appreciative," the singer said. "I have more respect for Perrie than to end anything over text message. I love her a lot, and I always will, and I would never end our relationship over four years like that. She knows that, I know that, and the public should know that as well. I don't want to explain why or what I did, I just want the public to know I didn't do that."
