Kyle Richards' 4 Daughters: Everything to Know While chatting with PEOPLE about her role in Halloween Ends last October, Richards opened up about her oldest two daughters' role on her husband's new reality show, and how she once said she would never allow her girls to follow in her TV footsteps. Noting how she is "totally eating my words" now, Richards told PEOPLE exclusively, "A few years ago, [I was quoted as] saying I would never let my daughters do reality television." "Here are those words coming back to bite me," she laughed. But, she explained, "because it's a business show centered around our company, The Agency, they decided to go for it. They are businesswomen, and my husband's a businessman." "I can't wait for the haters to be like, 'You said you would never let your daughters [be on TV],' " Richards added. "I already know, guys. I'm putting it out there. I said that."
