Rumors started to spread when the rapper abruptly canceled his AstroWorld concert in Buffalo, New York on Thursday. While Scott said it was due to illness, TMZ reported the rapper was in Los Angeles to comfort Jenner after she accused him of infidelity.
His rep denied the allegations in a statement to Entertainment Tonight: "Travis Scott vehemently denies he cheated on Kylie. It is not true. He did not cheat. He canceled one show tonight because he is under the weather."
The concert has been rescheduled for March 10.
Scott also tweeted an apology to his fans on Thursday, "Buffalo I’m so sorry I can’t perform tonight. I’m under the weather and it f--ing sucks! Can’t pull up without full rage. Show rescheduled to March 10 all tix are valid. See u soon."
This isn't the first cheating scandal to hit the Kardashian-Jenner family. Last week, news broke that Jenner's best friend Jordyn Woods allegedly hooked up with Khloe Kardashian's boyfriend and father of her child, Tristan Thompson. They share a 10-month-old daughter, True.
Woods reportedly moved out of Kylie's home and will no longer appear on the family's reality show, "Keeping Up with the Kardashians."
The 21-year-old model is expected to break her silence in a tell-all interview on Friday's episode of Jada Pinkett Smith's Facebook Watch series, "Red Table Talk." She posted a teaser video on social media earlier this week of her sitting at the table in a black dress.
