Lindsay responded: "Lisa, I love you but I’ve never even met him," she exclaimed. "I never met him, really, yes." She added with a nod to her Parent Trap characters, "Maybe he met, like, Annie or Hallie."
Cohen asked Lohan, "you’re calling Jax Taylor a liar?" to which Lohan replied, "yep, yes."
Meanwhile, Jax took to Twitter to react to Lohan's claims. The Vanderpump Rules star claims Lohan is the one that's lying and even shared a text exchange from one of his friends, who claims he was a witness to the rumored hookup.
"Not that I care, it was over 10 years ago and I am happily engaged... but She’s a liar, my two friends who have nothing to gain, were with me the whole night. That’s all I will say on this. So you are lying darlin. @Bravotv @PageSix"
