Most recently, there has been a whole lot of drama surrounding Bella and Selena.
It started when Selena 'liked' and commented a sweet message on Bella Hadid's photo on Instagram. "Stunning 😍" the singer wrote.
Bella was quick to delete the photo entirely from her Instagram feed, however, Selena (and the rest of the world) took it as a personal swipe toward her.
While Bella has still not commented on why she deleted the photo, the "Anxiety" singer assumed it had something to do with her, which eventually led to her fans calling out Bella for being 'immature' while Selena is on this journey to be the bigger person.
It didn't take long for Selena to jump in and defend Bella against her fans, asking them to treat her nicely after the hate rolled in.
But did Bella ask for her help? No, she never even admitted that deleting the photo had anything to do with Selena's comment.
Commenting on an article posted on @commentsbycelebs, Selena wrote: "I shouldn't of spoken without knowing the truth. I'm sorry. Please don't be hurtful. She is a wonderful person and it was all a misunderstanding."
It's a similar situation that Selena had herself in last month with Justin Bieber's wife, Hailey Bieber. Another enemy of Selena's.
After the Bieber's had their second and very lavish wedding, Selena quickly released "Lose You To Love Me", a single that shredded her relationship with Justin Bieber to pieces.
One may argue that the song release was far too close to Justin and Hailey's wedding, with the newlyweds not being able to enjoy their time as a married couple before an ex came in and stole the show.
However, Hailey was the one who copped a load of criticism from fans, after she uploaded an Instagram Story of her listening to the song "I'll Kill You," by Summer Walker.
Again, Hailey might not have been referring to Selena at all, but it was she who saved the day by swooping in to defend Hailey from her fans, asking them to treat her nicely.
Now, it seems like Hailey has taken this opportunity to weigh in on the newest drama between her friend Bella, and Selena. In a surprising turn of events, it seems like she might be taking Selena's side, showing her support of fellow women.
Posting to her Instagram Stories, Hailey uploaded a photo that read: "When girls are nice to each other, we're so much more powerful."
Selena's beef with Bella started when she started dating Bella Hadid's ex The Weeknd (Abel Tesfaye) in January 2017, two short months after the rapper broke up with Bella.
The pair broke it off in October that same year, with The Weeknd going back to Bella and Selena back to her ex, Justin Bieber.
Selena also has a very close alliance with Taylor Swift, the number one enemy of the Kardashian's - who are very close with the Hadid and Baldwin/Bieber's.
Bella Hadid and The Weeknd don't have the steadiest relationship, dating on-and-off-again the years following his and Selena's split, but maybe Bella's hostility has come from the fact that Selena recently reached out to The Weeknd, saying she misses him on Instagram.
At Kendall Jenner's 24th Halloween inspired birthday party recently, The Weeknd posed with model Emily Ratajkowiski in a photo booth, and Selena commented: "I MISS YOU GUYS!!!"
Yikes.
Selena actually re-followed Bella Hadid on Instagram not too long ago (with no follow back FYI). While many fans are applauding Selena's attempts in growing and showing her support for Bella, it doesn't exactly mean the model is obligated to being friends with her.
Bella has still not made comments on the situation.
