According to The Sun, who was first to report the duo's split news, they called it quits shortly after Harry finished his world tour earlier this month.
Just a couple of weeks ago, the French-American model was spotted supporting the British singer at his Los Angeles concert stop.
The pair reportedly was introduced by mutual friend and socialite Alexa Chung in 2017, but in an interview with BBC 1 Radio host Nick Grimshaw, the songster, 24, denied knowing the model, 28.
When shown a photo of Camille, Harry said that he hadn't met her but was "sure she's a wonderful person."
Harry is always known for keeping her relationships under wraps. As for the list of his girlfriends, he previously had affairs with food blogger Tess Ward, Keeping Up with the Kardashians star Kendall Jenner and songstress Taylor Swift, Bo' Selecta! star Caroline Flack and many more.
Camille, meanwhile, dated vocalist Andrew VanWyngarden, skateboarder Dylan Rieder, musician Cam Avery and singer Devendra Banhart.
