Photos: After 10 months together, Selena Gomez & The Weeknd break up

Selena Gomez and The Weeknd (real name Abel Tesfaye) have called it quit.

The duo, who started dating in January—have decided to go their separate ways, and it was a decision that was a long time coming. In fact, a source tells us they've been discussing the fate of their relationship since the summer.

"It's been hard for them to come to the realization that this is the direction things were heading, but it's been hard for months," the insider tells us. "They have been open and honest about it and where they were going. Distance definitely played a factor."

The news comes as no major surprise, considering Gomez's recent hang outs with her ex, Justin Bieber. 

 Gomez and Bieber were spotted hanging out at Gomez's home last weekend and again this weekend, grabbing breakfast and attending church together in Westlake Village, Calif.

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.
