“Love you wifey,” he added, using an affectionate nickname he’s called Jenner many times before, even though the pair aren’t married or engaged yet.
Although Scott made no direct reference to any cheating allegations, he told the crowd, “Remember to keep your family first,” TMZ reported.
Late Thursday afternoon, TMZ reported that the Keeping Up with the Kardashians star had accused her boyfriend of cheating on Wednesday, which prompted Scott to cancel his tour stop in Buffalo, New York, and remain in Los Angeles, where the couple got into an argument.
A rep for Scott went on to strongly deny to PEOPLE that he was unfaithful and that he and Jenner had a fight about cheating. A rep for Jenner had no comment.
The TMZ report came hours after Scott announced on Twitter that he canceled and rescheduled his concert due to illness.
“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,” tweeted Scott, who has been dating Jenner since April 2017.
Scott has since deleted his Instagram account, but his Twitter account remains active.
Shedding some light on why Jenner suspected Scott of cheating, a source recently told PEOPLE that the Kylie Cosmetics mogul has experienced trust issues amid the Tristan Thompson–Jordyn Woods cheating scandal.
“Kylie had a rough week,” the source said of the drama. “She is still devastated about Jordyn and had an argument with Travis after she checked his phone and saw something that she didn’t like.”
However, according to the source, “Travis says he didn’t cheat.”
As for what’s next for Jenner and Scott — who share daughter Stormi, 1 — the source said that “Kylie was upset at first” but “seems better” now.
“She isn’t breaking up with him,” the insider added.
