“My Instagram is pretty sexy, so I get a lot of comments about my body, which is nice. But he came in and messaged me something like, ‘You have the most beautiful smile,’ and sent me his favorite photo of me from my feed,” Kellar, 31, said.

“I was wearing a turtleneck in that picture,” she said. “It was really sweet of him.”

On Tuesday, Paul’s Most Valuable Promotions announced that Kellar would be one of the four ringside models.

This isn’t the first time Kellar has been a model for a Jake Paul fight.

Back in 2021, Kellar went viral when Logan appeared to try to flirt with her in the ring after Jake’s fight against Tyson Woodley.
