When they broke up two months ago, Bella Hadid probably didn’t think The Weeknd would be doing the naughty with anyone else anytime soon. Then came Selena Gomez who, according to a source, totally betrayed Hadid by hooking up with her ex-beau.

The gorgeous model is apparently feeling kicked in the chops after hearing the news that Abel Tesfaye (The Weeknd's real name) and Gomez got together two months ago. Which would kind of be around the time Bella and him parted ways… Yeah, that.

TMZ.com’s source also reckons The Weeknd and Selena spent Christmas together. Ouchie.

One source close to Bella told TMZ.com, Giving Bella and Gigi a heads up would have been the respectful and honourable thing to do ... but I guess that's just Hollywood."

Bella and her sister Gigi Hadid are even more annoyed because Selena reportedly didn’t even bother to tell them about her new love thing. Instead they had to find out about the pair dating online.

If true, that sucks all round.
