But this month Walsh tells More magazine that she feels like she has messed up by not having kids at her age (she's 43).
"I feel like a loser. I would definitely love to be a parent," Walsh tells the April issue of the mag.
But, unlike most single ladies in Hollywood, Walsh doesn't want to go it alone. "I definitely don't think I want to do it on my own. Things are just going to go the way they go...I thought I'd be married and have three or four kids. I always knew I wanted to be an actress, but I think I always wanted a quote-unquote normal life because I had a very untraditional upbringing."
Last year, Walsh's marriage from film executive, Alex Young, ended after just 14 months -- in a very public divorce.
"Oh my God. The worst thing ever. It was so public, and yet it was so legal-embroiled. You couldn't talk about anything," Walsh says.
But she says the entire process, the falling in love so quickly and watching things end even faster has taught her some valuable life lessons.
"I've always had the courage thing down, but then I had to develop the rest. I've learned to seek other people's counsel more. That's a good part of growing up," Walsh tells the mag.
Now that the sexy red head is all grown up and approaching her mid-forties she says she has to work harder on her shape than ever before.
"It certainly requires you to take care of yourself. But I like to eat food, and I don't diet," Walsh says. "I do Pilates, and hike with my dog. It's weird. As you get older, everything changes. Everything starts getting...looser. But I think it's important to accept that. I'm lucky. I've got pretty good genes. But I think it's a weird thing to fight it."
