After only a few months of dating, ET confirms that the singer and model have ended their summer relationship.
“It was not a dramatic breakup," a source tells ET. "They both were too busy and are working a lot the next few months. Before they dated, they were already good friends and they will definitely stay friendly. No bad blood there. It was amicable."
Gigi, dressed as Sandra Dee from Grease, attended Heidi Klum's New York City bash solo. An eyewitness at the event told ET that she was with two other guys that appeared to be just friends of hers.
Meanwhile, Joe appeared to be dealing with the breakup through music. This past weekend, the 26-year-old dressed up as a sad clown and performed a cover of Adele's emotional new track, "Hello," with his new band DNCE.
