Bob Saget's widow Kelly Rizzo is seemingly fed up with naysayers attempting to call her out for moving "too fast" following the public debut of her new romance.

Rizzo took to TikTok to clap back at her haters, saying, "This is something I have not addressed publicly, but I feel this needs to be said."

"The vast, vast, vast majority of all of the comments and feedback and support and everything I've gotten since Bob passed, 99 percent has been positive and lovely and wonderful," she said. "But there are some people who just love to talk."

The clap back comes after critics shamed Rizzo, 44, after the debut of her relationship with new beau, actor Breckin Meyer. Meyer, 49, is best known for his roles in films including 'Clueless,' 'The Craft,' and 'Road Trip.'

"Unless you are a widow, or are a widower, you truly have absolutely no place and no right to comment on this because you do not know what it's like." she said in her defense.

The 'Eat, Travel, Rock' star went on to explain how many people may not understand the "incredibly complex and difficult and dynamic thoughts and feelings that come up during this entire process" regarding losing a spouse.

The widower expressed the guilt and shame felt internally when it comes to the mere thought of dating, stressing that despite that she also felt "lonely" even with the support from loved ones telling her "it's okay."

In this situation, it was the support from Saget's daughters and friends that encouraged her to take the leap to move on romantically. 

She responded: "Whether somebody moves on a month after or 10 years after does not diminish or take away from the love and the relationship that you had with your partner."
