"I'm not weighing in on the Rachel/Raven drama. I could care less about that, not my business," he went on, according to Us Weekly. "What is my business is the countless number of times she's spoke poorly of me... including that time she ran her mouth about me to Cassie."
The NFL alum added, "Funny thing is I have never met her." It's unclear what Rachel allegedly said to Cassie about Colton, though she did once say, "I'm definitely not a big fan of Colton as 'The Bachelor'" in an interview before his season began.
Meanwhile, Rachel and Raven became close while competing on Nick Viall's season of the ABC hit series, but the two recently had a falling out. Neither side has explained why, and while Lindsay wasn't too forthcoming on "WWHL," it's clear whatever happened was bad.
"I can't say. I promised I wouldn't say," Lindsay told Andy Cohen after he revealed her beef with Gates was the most asked-about topic of the evening. "But it was enough for me to not want to be friends with her anymore. And I never will be."
Lindsay ended "The Bachelor" in third place and went on to star on "The Bachelorette," where she found love with her now-husband, Bryan Abasolo. Gates, on the other hand, was the runner-up of Viall's season. She got engaged to her "Bachelor in Paradise" co-star, Adam Gottschalk, in June of this year.
As for Underwood, the former "Bachelor" is still dating Cassie Randolph, who got cold feet about potentially spending the rest of her life with the athlete and quit the show during his season. That move prompted Colton's infamous fence jump.
