There might be some trouble in paradise for longtime couple Kylie Jenner and Travis Scott.

While Travis says that he canceled his Buffalo concert on Thursday (February 28) due to illness, TMZ is reporting that it’s because there are issues between him and Kylie right now.

Travis flew home to Los Angeles to spend the night with Kylie and their one-year-old daughter Stormi during his night off. While at home that evening, she reportedly discovered “evidence” that he cheated on her and a “major argument erupted.”

Travis‘ rep denies that he cheated. No other details were provided, but it’s definitely been a hard couple weeks for Kylie.

Last week, it was discovered that Kylie‘s best friend Jordyn Woods hooked up with her sister Khloe Kardashian‘s boyfriend Tristan Thompson.
