Things are heating up in hurry between Gigi Hadid and former One Directioner Zayn Malik!

It was just earlier this week that it was reported that the duo is dating with a source telling Us Weekly, "They seem equally super into each other, texting each other all the time. They've only been hanging out a couple weeks."

Now, it seems like they are in the puppy love stage and aren't exactly hiding their romance.

On Nov. 24, the couple enjoyed a date night at West Hollywood, Calif., hotspot The Nice Guy, where they joined Bella Hadid, Gigi's younger sister (Bella's boyfriend, The Weeknd, is on tour, so he wasn't on hand.)

Inside the venue, a separate source tells the magazine that the hot new couple was "inseparable." Gigi and Zayn came in with a group of friends and took over a booth, a source said, where they sat together holding hands and spent the night whispering to each other.

Gigi apparently didn't even leave Zayn's side when he left the table for a smoke break -- she joined him at an outdoor patio.

"They were laughing together and had an easy, good vibe," an onlooker said of the group.

For their date night, Gigi donned glasses, distressed jeans and a tummy-baring crop top. Zayn wore ripped jeans and T-shirt of punk rock band Social Distortion.

"He thinks she's so hot. He takes interest in her shoots and videos she does," a source said last week when it was revealed that they were dating. "He thinks she's sweet, too. She talks about her mom a lot and her family, and he likes that."

Really, she's a guy's girl.

"She drinks beers with the guys," the source said, "she's cool, and funny."
