Cody Simpson and Gigi Hadid have broken up yet again, and this time there are speculations claiming that the 18-year-old singer cheated on the 20-year-old model with either Kendall Jenner or Miley Cyrus.

According to Celebrity Dirty Laundry, while a rep for Simpson and Hadid released a statement claiming their second breakup was due to their busy schedules, there are certain rumors claiming that Cody may have cheated on Gigi.

It wasn't made clear whom he cheated with, but since the split, Simpson has been spotted going out with Kendall Jenner and Miley Cyrus leading some people to question the nature of his relationship with the "Keeping Up With the Kardashians" star.

However, Cody Simpson's alleged cheating scandal appears to be very questionable since Daily Mail pointed out that the Australian singer looks downcast since his split from Hadid. 

Simpson was rocking the stage in Netherlands on Sunday when fans noticed that he looked gloomy while performing after breaking up with his girlfriend of two years.

That morning, a rep released a statement to E! News to confirm that the young couple have split.

"Cody and Gigi want each other to be in a place right now that allows him to only focus on his music, fans, and new message, while she can focus and continue building her career," Hadid's rep said in the statement.

The statement then went on to say: "They love each other dearly and have split up in hopes that growing on their own paths will bring them together in the future. They remain friends with no hard feelings and each other's biggest supporters." 

Meanwhile, since their split, Gigi Hadid didn't waste any time to hang out with her girlfriends. 

The supermodel was seen hiking with girl bestie Taylor Swift on Sunday. The two female celebs enjoyed a long talk during their hike, according to Pop Sugar.

It wasn't clear though if they were talking about Simpson or about Swift's upcoming music video for "Bad Blood," which features Hadid.
