World famous tennis player, writer and now perfumer, Serena booms

Serena Williams, after releasing in March her second book with Sister Venus, titled, "Venus and Serena, Serving From the Hip: 10 Rules for Living, Loving, and Winning," already with her own fashion company, has added cosmetics to her game.

Calling herself a "beauty junkie," the tennis star announced Thursday she has signed on to be the next "guest creator" for Flirt! cosmetics.

"I've always been a beauty junkie," Williams told The Associated Press. "I've tried every product. I'm addicted to products. I can't go into the mall without buying everything. I said to my manager, `I should get a beauty deal; I'm going to go broke buying all these products."

Williams, who will compete at the U.S. Open next week, said she had multiple offers but that she decided to go with Flirt! which is produced by Estee Lauder and sold only at Kohl's.

"Flirt! fits my personality. It's young, colorful, funky, cool it's a great fit for me."

Among the products that will have Williams' stamp are lip glosses that are attached to necklaces, which will be in stores February. Williams also has a fashion company named Aneres, her name spelled backward.

She even wears makeup on the tennis court, but not much because of the few waterproof cosmetic products on the market. "Maybe that's next for me," she joked, reports the AP.
