She's one of the world's most magnificent creatures, yet there are those who maintain that Tyra Banks isn't all Tyra. They say that because she's well developed, there's some silicone behind them thar' developments. Not so, says Tyra. "A lot of people think I have breast implants because I have the biggest boobs in the business," she affirmed to "Details" magazine. Tyra admits, and with hint of pride, that she's size 34C and has been so endowed since high school. She also claims that the "push up" bra is what creates the illusion. When she gets home, she says, and takes off the bra, no one would think they were fake any more. They sure look real to us. Besides, plastic surgery just ain't her style.
