Happy Birthday, Valerie Bertinelli!

Valerie, who began entertaining us in the 1970s as the teenager Barbara Cooper in “One Day At A Time,” turns 52 today. These days, she’s playing Julia Moretti on the hit series “Hot In Cleveland,” also starring Betty White, Wendy Malick and Jane Leeves. But there are a few other things about her life that you might not know:

She's A Great Runner

After years of struggling with her weight and health, Valerie ran the Boston Marathon in 2010, raising money for the Dana-Farber Cancer Institute.

She Starred In A True Reality Show “One Day At A Time,” which starred Bonnie Franklin as well as Mackenzie Phillips and Valerie, was based on the single-mom-and-daughter experience of Whitney Blake, the show’s writer. Blake’s daughter is actress Meredith Baxter.

She Had An A-List Boyfriend Valerie’s most famous relationship is probably her stormy marriage to rock star Eddie van Halen. But she dated another famous guy years before: Steven Spielberg.

She's Got Some A-List Co-stars This year, she’s getting a star on the Hollywood Walk Of Fame. Her fellow honorees include Jennifer Aniston and Scarlett Johansson.

Her Son Has A Unique Name She and Eddie have a son, Wolfgang, who plays in his dad’s band. Wolfgang van Halen is possibly only the second guy in history to have that name – the other being Mozart.

She's Very Loyal Although she and Eddie (at right in photo) broke up a while back, Valerie still plugs his records and tours on her website (www.valeriebertinelli.com).

She's Had A Lot Of Weight Problems Valerie, whose weight has gone up and down over the years, was a perfect spokesperson for diet giant Jenny Craig, regularly appearing at events to cook healthy versions of classic favorites (left). She’s been painfully honest about her issues with weight and wrote a book, “Losing It,” that chronicled her struggles. Her conclusion: "I've realized that I'm more important than food is. I love a big slice of pizza, but I love myself more. Being thin is about changing the way you think about yourself. It's about saying that you deserve to be healthy."

She's A Stress Exerciser Before marrying her current husband, financial adviser Tom Vitale (left), last year, Valerie was so nervous that she ran three miles on the treadmill just before the wedding.

She Would Really Appreciate A Visit From Her Higher Power Valerie believes in a Higher Power, and that the Power has visited her but should come around more often. "I have experienced days of inner peace and connectedness with a larger spirit—twice," she writes. "Why not more often?"
