ABC News' Amy Robach and Natasha Singh report:

Some call her the First Lady of Rock, but throughout the years, Sharon Osbourne has made another name for herself.

Her latest venture is a children's book, the first she's written, called "Mama Hook Knows Best."

"It's trying to find the right balance of keeping little ones entertained using words they can understand, and also giving a good message so that the story is fun but at the end of it, they take away something," Osbourne, 60, told ABC News.

Osbourne says she even plans to give a copy to her good friend and first-time father-to-be, Simon Cowell.

"Absolutely, I'm going to give it to him," she said. "He'll be a great dad. I think he will love [fatherhood] and probably have many more kids."

The children's book is based around a popular Disney cartoon in which Osbourne voices "Mama Hooks," the mom of Captain Jack, a pirate.

"I think I am a pirate because I never live somewhere for very long," she explained. "I'm always traveling, always off somewhere."

Osbourne does indeed work a lot, juggling being a talk show host, a talent show host judge, a music manager and a mom of three.

"It is a family tradition," ABC News' Amy Robach said to Osbourne. "You are all working, a lot."

"I think it's something that's inbred from Ozzy and I because we were both working at very young ages. So it's a trait that we have instilled in our children, a good work ethic," Osbourne explained.

Part of that ethic is ensuring her children work for what they earn.

"They've never been the type to show up to a club and say, 'Oh, I'm not a member here, but do you know who I am?' They would cringe at behavior like that," she said. "They're not that way. I just want people to know that they're normal, no sense of entitlement, they work their little butts off for what they get, they don't get handouts, they're not trust fund babies and they've made mistakes. We all do, and we all learn from those mistakes."

When asked if it's harder raising children as a celebrity, keeping them well-mannered, successful and un-entitled, she replied, "That's the right word, is 'entitlement' because so many children who are brought up in privileged homes, whether you're a celebrity or not, have a horrible sense of entitlement. It's something that I have always had great disdain for, that sense of privilege without you actually having done anything to earn that."

Jack Osbourne 'Dancing With the Stars' to Shine Light on Multiple Sclerosis

This year is a big one for the Osbourne family. Their youngest child, Jack, 27, who was diagnosed with multiple sclerosis last year, is preparing to waltz back into the limelight as a contestant on "Dancing With the Stars."

"He has never danced a step in his life," Osbourne laughed, although she's not surprised by his decision to participate in the show. "He discussed it with us all and said he wanted a platform to inform people around the world that if you do have a disability or you have MS, you can still do things that everybody else can do."

And her daughter, Kelly, 28, is soon to walk down the aisle.

"Well, Kelly, I love her for this," said Osbourne. "She's like, 'Oh, Mom, I can't be doing all these arrangements, and, You have to do this and that, just do it and I'll turn up.' And I'm like, 'Really?' And she's like, 'Yes, you just do it.' And I'm like, 'done.'"

It's clear that Osbourne is in a good space these days, but after battling cancer and undergoing a double mastectomy, she has learned that what matters most is family.

"Being a celebrity, this never lasts. It never does," she said. "But your family does. That I think is my greatest achievement and my greatest gift."
