Is Bella Hadid upset with Selena Gomez? Hadid apparently unfollowed the "Hands To Myself" singer on social media shortly after PDA photos of Gomez and The Weeknd went viral.

Elle.com reports that Hadid was still following Gomez at around 1:30 p.m. But two hours later, she appeared to have unfollowed the singer. However, Hadid still follows The Weeknd, and Gomez still follows Hadid.

As Elle noted, Gomez and Hadid have been friendly in the past. They posed for a cute Twitter photo together back in 2015. And Hadid was one of several stars who liked Gomez's picture when she returned to Instagram last month.

However, E! News says that Gomez and Hadid are not that close. So it's not like The Weeknd is trying to make his ex upset by going out with one of her friends.

In fact, Hadid and The Weeknd still have love for each other since splitting up in November. They even briefly reunited at the Victoria's Secret Fashion Show just weeks after the breakup.

"There is no awkwardness," Bella Hadid said at the time. "He is my best friend, and I am excited because I am walking during his performance."

Still, Hadid and Gomez are in the same group of friends. Gomez is close to Taylor Swift, as is Hadid's sister Gigi. And, of course the Hadid siblings are really close. So there may be some tension next time Swift's squad gets together.

Hadid unfollowed Gomez just hours after photos showed The Weeknd making out with the singer outside Giorgio Baldi. "It was a romantic dinner date in the rain," a witness told People. "They acted like a couple. They ordered pasta and shared the food. She seemed very into him  — she was smiling a lot. They left holding hands."

A source told People that this romance is "new and nothing serious." But E! reported that The Weeknd has "always had a thing for Selena."
