Tennis superstar Andre Agassi insists his famous '80s mullet wasn't a style choice, but rather the symbol of a young man trying to figure himself out.

In a new interview with VEGAS magazine, on shelves now, he talks about his rebellious side as revealed in his recently published memoir, Open.

"My behavior, the way I acted or the way I dressed or the things I said, was so outrageous at times, so bizarre, that people naturally thought I was expressing myself," he tells the magazine. But he says those things were ways of hiding his insecurities. "...I was exploring myself, trying to figure it all out. Which is one of the things I wanted to say with my book: That wasn't me under the mullet. That was someone trying to figure out what 'me' meant."

He goes on to explain: "My early rebellions were attempts to hide, to distract people from my own insecurity. I was scared," The image, he says, "was me trying to keep the game and the people from changing me ... it's a big difference and an important one."

Meanwhile, he suggests that his next book could be a love story. He says of wife Steffi Graf, "She's very private, but she's also very tolerant of my public side. I could write a whole book about her patience and her acceptance and her kindness, her love."
