Selena Gomez 'doesn't care about Bella or Gigi' Hadid amid photos with Bella's ex, The Weeknd

Looks like there's some bad blood growing between Bella Hadid and Selena Gomez in the wake of the new-infamous photos of Gomez and Hadid's ex, The Weeknd, making out in Santa Monica.

Us Weekly reports that "Bella still wants to be with him" and warned her ex that she thinks Gomez is "using" him, though Gomez couldn't be bothered.

"Selena doesn't have any reservations about hooking up with Bella's ex," the source told Us, noting that the pair has been recording "sexy" music together. "[She] doesn't care about Bella or Gigi."

Hadid and The Weeknd mutually broke up back in November, nearly two months before said photos were released to the press, but it sounds like there are unresolved feelings involved. The former couple cited busy schedules for their split.

Though both Gomez and Hadid have been connected to Taylor Swift's notoriously large friend group (or "squad"), neither has been known to hang out with Swift a ton lately, so that supposed connection doesn't appear to be impacting either star's decisions.

"She doesn't really hang out with Taylor's crew," a source explained to Us.

As for Swift herself, it appears as though she "won't pick sides, since she gets along with everyone and wants to keep it that way." Of everyone involved in the allegedly dramatic situation, Swift is closest to Bella's older sister, Gigi. Her duet with Gigi's boyfriend, Zayn, "I Don't Wanna Live Forever," is currently climbing the charts.
