On Sunday, tennis superstar Maria Sharapova won the Porsche Tennis Grand Prix for the third year in a row -- an accolade she adds to her four Grand Slam titles. (Pretty impressive, huh?)

Maybe I shouldn't have been surprised when she needed a couple extra days to answer my burning questions about style and beauty.

When she got back to me earlier this week, I was also surprised by some her answers. Of course she loves sunscreen (she just became a co-owner -- not a celebrity spokesperson -- of Supergoop!), but she doesn't seem to fully grasp her role as a style icon. Over the last few years, she's looked as good on the red carpet as she has on the courts -- and everyone from Vogue to Joan Rivers has appreciated her sartorial choices.

Whether it's a cool printed dress or sporty separates -- accessorized with sunscreen, naturally -- this girl's always winning.

1) TB: Describe your personal style in 10 words or less.
MS: Simple, practical and easy.

2) TB: Who are your style icons?
MS: Audrey Hepburn is one of my greatest style icons.

3) TB: What's the best beauty advice you've ever received and from whom?
MS: At a very young age, my mom told me "your skin won't be young and smooth forever," which is why I made sure sun protection was always part of my daily beauty routine. Broad-spectrum sun care is a vital preventive measure in fighting aging, and more importantly, we all should be more conscious about making UV protection a healthy daily habit. Just like I go to the gym every day, I always apply UV protection.

4) TB: What's currently in your makeup bag?
MS: I keep my Supergoop! SPF 30 City Sunscreen Serum with me at all times since that is what I use every day. The formula is so luxurious and lightweight that I don't even want to wash it off at the end of the day! I also must always have my Oribe Dry Texturizing Spray for last minute fix-me-ups.

5) TB: What advice do you have for young women in sports?
MS: Find a sport that you are passionate about and stay focused on your own game. Stay true to working hard and achieving your goals.
