WATCH: Carly Fiorina goes bonkers after desperate attack on Hillary Clinton's marriage
Fired HP-CEO Carly Fiorina on Hardball (MSNBC screencap)

In an interview with MSNBC's Chris Matthews, following the so-called "undercard" debate for the GOP also-rans, former HP CEO Carly Fiorina launched a vicious and personal attack on Hillary Clinton that clearly disgusted the Hardball host.

During the debate, Fiorina sniped at Clinton without mentioning her name, saying, "Unlike another woman in this race, I actually love spending time with my husband."

Pressed by Matthews whether the Clinton's have a "real marriage," Fiorina smirked and repeated, "They've been married for a really long time," over and over again as he rephrased the question.

After being accused by Matthews of avoiding answering the question, Fiorina went off the rails as she attacked the Democratic front-runner while an appalled Matthews looked on.

"There are so many other things we could talk about like the fact that Mrs. Clinton wants to go to the White House -- she's qualified for the big house," Fiorina said as she dropped all pretense of fake smiling for the camera."She should be prosecuted. She has not been prosecuted for things that took a great warrior out of office, David Petraeus."

"So let's talk about that, Chris," Fiorina continued. "Let's talk about how amazing it is that this woman, that cannot be trusted, who should have been prosecuted by now, has just raked in more money than any single candidate."
