Is Selena Gomez upset about The Weeknd's recent reunion with Bella Hadid? It sure seems that way.

While Gomez wasted no time moving on from her 10-month relationship with the "Reminder" singer with Justin Bieber, who she dated exclusively for two years, she quickly took a stand against The Weeknd on social media after he was caught with his own ex.

On Nov. 17, Hollywood Life revealed that Gomez had unfollowed The Weeknd on Instagram just after he was photographed sneaking out of Hadid's apartment in New York City on Tuesday night. As fans will recall, The Weeknd dated Hadid until November of last year, just two months before he went public with his romance with Gomez.

A short time after The Weeknd was seen making his way out of Hadid's home, an insider told E! News that he and the model have been hanging out and still have feelings for each other.

"Bella and Abel have been in contact since Abel and Selena split, but they are not back together," a source explained. "Abel reached out to Bella asking to hang out and catch up, and she decided to see him and see where things go. She knows that if they don't date again, they can at least be good friends."

There's no denying their "amazing connection. They enjoy each other's company and have a lot of fun together," the source added.

According to the report, The Weeknd has let Hadid know that he still loves her and apologized for the pain he caused her in the past. However, while Hadid reportedly still loves The Weeknd, the insider said that she has her guard up since she never truly got over him.

As for what may happen between The Weeknd and Hadid, the model is reportedly not on board with involving herself in an exclusive relationship at this point in time. Instead, she wants to be friends with The Weeknd because she knows his busy touring schedule won't leave him with a lot of time to tend to a potential romance. Hadid also is reportedly convinced that The Weeknd may be talking to a number of other women.

Meanwhile, Selena Gomez and her former boyfriend, Justin Bieber, appear to be going strong weeks into their reunion and are frequently seen alongside one another in Los Angeles. They were first seen together in late October.
