There seems to be bad blood in the air for Kansas City Chiefs tight end Travis Kelce.

Kelce’s ex-girlfriend, Maya Benberry, has a cryptic warning for pop icon Taylor Swift.

Maya Benberry dated the Kansas City Chiefs player for only a few months back in 2016 after winning his E! reality dating show, “Catching Kelce.” Now, Benberry is sending a stern warning to Swift.

Benberry claims that “the man [she] knew him to be when [they] dated” is an unfaithful one.

“Taylor [Swift] seems like such a fun girl with a beautiful spirit, so I wish her the best of luck, but I wouldn’t be a girls’ girl if I didn’t advise her to be smart!” Benberry, 31, told DailyMail. “I’m sure by now she has mastered the ability to see who is there for her — and who is just using her.”

She added, “Only time will tell, but like the saying always goes: Once a cheater, always a cheater.”

Benberry previously seemed to accuse Kelce of cheating on her with his next girlfriend, Kayla Nicole.

“When you and your ex broke up five months ago, but you find out via social media that he’s supposedly been in another relationship for 6…” she wrote in a since-deleted Tweet, per Page Six.

Kelce dated Nicole for about five years, but they finally broke it off in 2022.

This warning from Benberry comes days after Swift was spotted hanging out with Donna Kelce, the mother of the Kansas City Chiefs tight end, at Arrowhead Stadium for the game against the Chicago Bears. After the game, the two of them could be seen leaving together before heading off to dinner.
