Here's some deep-rooted bad blood we didn't even know existed.
Bachelor and Bachelorette host Chris Harrison appeared on Access Hollywood Live recently to chat with hosts Billy Bush and Kit Hoover, and during his time on the show, the trio decided to play a little game of Let's Set Chris Harrison Up With One of These Famous Ladies.
The pair presented the newly divorced gent with a lineup of single ladies, including Denise Richards and Sandra Bullock among others, but when Bethenny Frankel came on the screen, there was no ifs, ands or buts about it—Harrison is not a fan.
"I knew her dad. I loved her dad," the 43-year-old revealed. "She didn't love her dad, but I loved her dad more. Her dad was a great Hall of Fame horse trainer, Bobby Frankel."
He continued, "I didn't like how she treated her dad after he passed away...no, no, switch." Yikes!
Fans of The Real Housewives of New York are aware of the strained relationship Frankel had with her estranged father (who split from her mother Bernadette after Bethenny's birth) leading up to his death in 2009.
In an episode of the Bravo series back in 2010, viewers witnessed Bobby losing his battle to cancer, and saw that he initially refused to see Bethenny after she flew from New York City to L.A. to visit him. However, he had a change of heart and called his daughter, asking her to come back. She did.
Bethenny discussed the final meeting with co-star Sonja Morgan, telling her that Bobby revealed to her that he had a "full life." Frankel chose not to go to her father's funeral.
E! News has reached out to Bethenny for comment.
