The reality star - who appeared alongside Fedotowsky on the last season of The Bachelor - was asked by Extra's Terri Seymour if she had been watching the new series.
"I have not been watching but I've been listening," she replied. "I've heard what has been going on."
Seymour then asked which of the final two contestants - Roberto and Chris L - Girardi preferred, prompting her to say: "I think Roberto is hot, so choose Roberto!"
Girardi also revealed that she has had to grow a "thick skin" to deal with the media attention that comes from being in the industry, pointing out that she is from a "small town" that is not used to paparazzi or tabloids.
"I just want people to know me for who I really am," she said. "I think I'm a caring person, a very giving person. I have a huge heart and wear my heart on my sleeve."
Girardi - who split from fiance Jake Pavelka in June - recently hosted a 'Fabulous And Single' party with friends in Las Vegas.
The Bachelorette: Men Tell All airs this Monday at 8/7c on ABC.
