"They are still talking and will remain friends," our source adds. "They have been very grown-up about it."
The news comes as no major surprise, considering Gomez's recent hang outs with her ex, Justin Bieber. However, our insider says Bieber "did not play a factor" in Gomez's relationship with The Weeknd coming to an end.
Our source said Gomez and The Weeknd split before she met up with Bieber on Sunday and further confirmed there's "nothing romantic" going on between them. Still, another source noted that The Weeknd was "upset" to see them hanging out "twice in the same week."
Meanwhile, Gomez and The Weeknd first sparked dating rumors after they were spotted kissing in Los Angeles in January. After that, they took their romance public, often photographed showing major PDA at events and dinners across the globe.
They attended Coachella Music and Arts Festival together as well as the 2017 Met Gala. Most recently, the couple shared a sweet moment at New York Fashion Week in September, smooching on the carpet ahead of the Harper's Bazaar party.
The Weeknd previously dated Bella Hadid for a year before they split in Nov. 2016, and Gomez dated Bieber for three years, from 2011 to 2014.
