Jonesing For Revenge! Gigi Hadid Caught Flirting With Ex's Brother Nick Jonas After Zayn Malik Backtracks On Her

Zayn Malik, 23, was spotted leaving the Warwick nightclub alone in Hollywood on Feb. 18 — another night of partying without 20-year-old Gigi Hadid.

The hot pair hit the skids on their relationship recently when Zayn called Gigi a "good friend" during an interview about his new album, leaving Gigi fuming about him denying their status.

The Victoria Secret's model immediately looked for revenge — and what better dagger than flirting with her 26-year-old ex's (Joe Jonas) brother, Nick Jonas, 23.

"He and Gigi seemed very close," a source told Heat magazine. "They were pulling each other near whispering and acting very touchy-feely. She's always had a crush on Nick."

"At one point, she rested her head on his shoulder. At the end of the evening, they went their separate ways, but they clearly had a fun night," added the insider. The report even said it wouldn't be the first time Gigi and Nick have gotten close — the magazine claims that Nick and Gigi hooked up before she went exclusive with Joe.

"Right now, Gigi is angry at Zayn and out to make him jealous. They're still officially dating, and she'd like to make it work, but Gigi's hot property and there are loads of guys dying to date her,” the insider told the magazine.
