The couple - who ended their engagement last month - became embroiled in a war of words during a post-split interview with Chris Harrison on last night's Bachelorette.
"I'm so mad at you. I'm so disgusted with you. You sold me out to a magazine for payment and then flirted with me all weekend," he told Girardi.
However, Girardi responded by saying that she wasn't trying to "bash his character or accuse him of anything" and defended her decision to talk to the press by saying she wanted to tell her side of the story because she thought Pavelka would also be telling his.
The pair also clashed on the issue of who initiated the break-up, with Girardi claiming she did it in a phone call and Pavelka insisting that it was him.
Other topics covered in the interview included Pavelka's stint on Dancing With The Stars - with Girardi claiming the couple never saw each other during filming, and Pavelka saying that she was excited to appear on camera in the finale.
