Dominique Moceanu: From Gold Medalist to Mom

Now, Moceanu's life is free of drama, control issues and secrecy -- almost. "I ... grab this letter, and I didn't recognize the name, but I thought, 'Who could be writing me a letter at my home?' Most of my fan mail came to the gym," Moceanu said. "Then I said, 'OK, there's a letter in here, let me read the letter.'" Watch "20/20" Friday at 10 p.m. to see how the letter changed her world.
