Are Taylor Swift and her model bff Gigi Hadid feuding over Joe Jonas? That seems to be case according to report as it claimed that Calvin Harris' girlfriend is mad at her friend for breaking the "girl code."

In a report by Celebrity Dirty Laundy, it was revealed that the "Blank Space" singer is not a happy camper as Taylor Swift is "concerned her former pal Gigi Hadid totally violated the code by hooking up with Joe Jones, one of her exes."

Gigi Hadid used to date Cody Simpson but they split last May. The break up is reportedly amicable, per the statement issued by the model's representative. Accordingly, the former couple "remain friends with no hard feelings and each other's biggest supporters."

After her highly publicized relationship ended, Gigi Hadid immediately made headlines when she was spotted getting cozy with Taylor Swift's ex-boyfriend, Joe Jonas.

Celebrity Dirty Laundry went on to say that while no confrontation may ensue between the two friends, Calvin Harris' girlfriend may do something petty.

"She would never actually confront Gigi head on, instead she will most likely do something petty like invite all of Gigi's friends except for her to some sort of event or party just to let it be known that they feuding," it said.

"Or maybe she will write another catchy song about her 'friends' stabbing her in the back - and make it very clear that it is about Gigi. Then again, Taylor may go a more traditional girl-fight route and just gossip behind Gigi's back and let everyone know that she is not happy about her dating Joe Jonas," the report added.

However, the alleged Taylor Swift, Gigi Hadid feud may just be rumors as the singer has reportedly gave her blessing to her bff to date Joe Jonas.

Per Hollywood Life's source, "She's given Gigi and Joe her blessing and believes they're great together. Taylor doesn't want the dynamic in her relationship with both to change."
