IN THIS ISSUE: Paris Hilton Turns 30 — Ready For Baby!

Sitting down with OK! on her 30th birthday on Feb. 17, Paris Hilton proves there’s no such thing as a day off. Over the past decade, she’s morphed from party girl to worldwide reality star in charge of 17 product lines. The little-girl voice, pink tracksuits and tiaras are gone, but the reality show cameras are back, catching every moment for her new  Oxygen reality show, The World According to Paris. We've got the exclusive in this week's issue!

Looking back at your 20s, do you wish you’d done anything differently?

In your 20s, you definitely have learning  experiences. I wouldn’t change anything because I feel like it’s made me the person I am today. I feel grown-up and excited about life.

What made you decide to do another reality show at this point?

I’m ready to show who I am. I’ve never done a show like this — letting so much access into my life. It shows my family, my boyfriend, my best friends, my daily life and my work — everything.

So is the real you different from the girl we saw on The Simple Life?

Definitely. The Simple Life was my first time doing reality TV. You start off with that character and then continue doing it. I’m kind of a shy person so it was easier to sort of hide behind that character. Now, I feel like it’s the perfect time to do a show like this.

What would people be surprised to learn about the real you?

I love to cook and can cook pretty much anything. Before, I would just eat everything and have fast food all the time. I only eat organic food now. My signature dish is lasagna.

Do you ever think about moving into fashion or humanitarian work full time?

I’ve gotten even more involved in philanthropy work in the last couple of years. I get to do everything I love through my show and designing my fashion lines. One day, I’d love to get into real estate and open my own hotels, something that reflects my personality.
