Gigi Hadid and Joe Jonas have broken up, PEOPLE has learned.
"Joe and Gigi’s relationship recently ended," a source says. "Nothing serious happened ... it wasn’t a dramatic break up. It was just hard to make it work with their schedules. They will definitely remain friends."
The supermodel and musician began dating this summer and were first spotted getting cozy at a New York bar in June. They made their red carpet debut as a couple at Global Lyme Alliance inaugural gala in New York last month, when Hadid's mom, The Real Housewives of Beverly Hills' Yolanda Foster, was honored for her advocacy work.

"She had a megaphone. She was a badass," Jonas, 26, told PEOPLE. "Everybody really looked up to her to lead and she really came through and showed us that she could do it."
But the stars seemed to spend Halloween apart, with Hadid going solo to Heidi Klum's annual party in N.Y.C. And on Tuesday night, a single Jonas hosted a Birchbox Man dinner for Movember in Los Angeles with his brother Nick Jonas and bandmate Cole Whittle.
Hadid previously dated Australian singer Cody Simpson off and on, and Jonas was last linked to model Blanda Eggenschwiler.
