ET breaks down what's gone on since the model unfollowed the 'Same Old Love' singer, who is rumored to be dating her ex.
It looks like Bella Hadid isn't too happy with Selena Gomez right now.
After the "Can't Keep My Hands to Myself" singer was spotted kissing Hadid's ex-boyfriend, The Weeknd, during a PDA-filled date night in Los Angeles last week, multiple reports have surfaced suggesting there's bad blood brewing between the two girls, who are both members of Taylor Swift's tight-knit "squad."

Hadid, 20, and The Weeknd (real name: Abel Tesfaye), 26, dated for nearly a year and a half before calling it quits last November. While chatting with ET backstage at the Victoria's Secret Fashion Show later that month, the model said the two have remained “great friends” since the split. But now, it appears things have changed drastically. Since news broke of The Weeknd's rumored romance with Gomez, Hadid seemingly sent a clear message to the pair by flipping the bird to paparazzi in New York City. She even went so far as to unfollow the 24-year-old actress on Instagram just hours after the steamy pics were released.
"Bella has reached out to Abel a few times and told him Selena is using him," a source close to Hadid reportedly told Us Weekly, revealing that the model "is pissed" about the situation. "He thinks [Bella's] just jealous and isn't listening to her."
A similar report from TMZ alleges that Gomez's famous on-again, off-again ex, Justin Bieber, also thinks the pop star is using The Weeknd for promotion, alleging that the two are working on new music together. "It seems [Selena] dates stars with whom she wants to collab [with]," the site reported, claiming Gomez has done this before with Bieber, Nick Jonas and Zedd.

Citing a different insider, People claims Hadid's not only "pissed," but "hurt" that her ex moved on with Gomez so quickly. "[Bella and Selena] have always been friendly, but they're not best friends," the insider reportedly told the outlet. "They've never been close."
Another source recently told E! News that Hadid is "actually not over The Weeknd."
"She still loves him," the source claimed. "It really hurt her seeing Selena be all up on her man. She still feels like they have a connection."
Meanwhile, Gomez appears to be on cloud nine, and has been spending a lot of quality time with her close pals. On Tuesday, she stepped out for dinner with a few of them at Boneyard Bistro in Sherman Oaks, California.
The former Disney star looked as happy as ever while sipping on an iced coffee at the beach during a recent girls' day out with her friend, Simi Khadra, who makes up one half of DJ duo Simi and Haze.
But here's where it gets interesting. The 22-year-old entertainer and her twin sister, Haze, also happen to be BFFs with Hadid and her older sister, Gigi…
Perhaps the siblings are just trying to play peacemaker?
