Sarah Ferguson will hit the damage-control talk show circuit Tuesday when she appears on The Oprah Winfrey Show. Just days after news broke that she tried to sell access to her ex-husband Prince Andrew, Ferguson will tape the interview on Friday. She is expected to downplay the incident as a momentary lapse in judgment. "We all make mistakes," she said Wednesday night at the launch of her new line of children's books. "Yet we go on. We dust ourselves down."
