Jake Pavelka and Vienna Girardi's reunion got ugly when Girardi stormed out in tears during their heated he-said, she-said confrontation.
When Bachelor host Chris Harrison asked Girardi, 24, if she had any regrets about their seven-month relationship, Girardi was apologetic about how she handled the aftermath of their split. (Watch a clip above)
"I am sorry that I went about it the way I did," former Hooters waitress Girardi tried to tell Pavelka, 32. "But I know you, and I knew you would have [sold your story to a tabloid] if I didn't."
As Pavelka replied, Girardi interrupted him, causing him to snap. "Please, stop interrupting me!" he shouted.
Crying, she stormed out: "He is the biggest liar I've ever met in my life!"
Said Pavelka, "Unfortunately, that’s what one of our arguments looks like."
