Kendra Wilkinson has a major regret.

Kendra Wilkinson & Hank Baskett Relive Their Worst Fight

During a new airing of WatchIt with Kendra and Hank, Wilkinson and her husband, Hank Baskett, are seen looking back on previous episodes of their reality show. During one scene, via Wetpaint Entertainment, Wilkinson dissed her former Girls Next Door co-stars, Bridget Marquardt and Holly Madison.

"I'll never forget them making me so scared, because they went, 'We don't wear anything twice within six months,'" Wilkinson was seen telling Jessica Hall, who responded, "Oh my god."

Holly Madison Reveals The Plastic Surgery Pressures Of The Playboy Mansion

Wilkinson lived with Marquardt and Madison at the Playboy mansion for several years, and starred alongside the women in the E! Network's Girls Next Door. At the time, all three of the women were girlfriends of the magazine's founder, Hugh Hefner.

Looking back, Wilkinson told her husband she was disappointed in her catty behavior.

"I forgot I said that," she explained. "To be honest with you, I don't like what I just said right there. I don't like that I, um, I feel bad talking about Bridget and Holly right now, like, about how we don't wear stuff at the same time. I was just moody that day, and I shouldn't have brought that up. I don't like talking about them. I don't like talking even bad about them. It's just, like, I was moody that day."

WatchIt with Kendra and Hank airs tonight at 9 p.m. ET on WEtv.
