Reportedly, Bella was still in love with him and immediately unfollowed Selena on IG after learning about their relationship.
And she isn't letting it go.
The Lose You To Love Me hit maker was not too happy about finding out her attempt of burying the hatchet with her former flame The Weeknd's ex girlfriend was not welcomed.
"She is about supporting women", the fan account wrote over the weekend. However, shortly after, Bella deleted the photo, and so the comment disappeared with it (Luckily, Comments by Celebs took a screen shot WHICH YOU CAN SEE HERE).
But, soon after Selena left the comment, Bella deleted the entire post.
Her comment fell on deaf ears, and the singer has expressed her disappointment.
Gomez made headlines last month for re-following Hadid on Instagram after their The Weeknd drama.
2 shot at New Jersey high school football game
Michael Mack and Shahid Dixon, both 27, Tyrell Dorn, 28, and Vance Golden, 26, were all charged with various weapons offenses. The shooting comes two months after two teens were shot during a football game at Philadelphia's Simon Gratz High School.
Anyway, Selena and The Weeknd called it quit in October 2017. Selena recently re-followed Bella on social media after unfollowing her when she was linked to The Weeknd.
The 27-year-old "Texican" pop star had followed the half-Jordanian, half-Dutch beauty back on November 6 three months after her second split with The Weeknd.
Selena doesn't have the best rep with Bella's crew, seeing as Bella is close with Hailey Bieber - Justin Bieber's wife. However, Gigi and Selena are both close friends of Taylor Swift.
With his exes in contact with each other yesterday, Selena Gomez's reaction to Bella Hadid's deleted Instagram post has us doing some serious Monday afternoon analysis.
Bella has yet to comment on the speculation.
