Earlier this morning in federal court, Martha Stewart was sentenced to five months in prison for insider trading. After doing her time, she'll serve another five months under house arrest and two years of "supervised release," which, I think, is legalese for probation. "I'll be back," Stewart vowed in a press conference afterwards. "I'm not afraid. Not afraid whatsoever. I'm very sorry it had to come to this." The domestic goddess, who could have gotten up to 16 months in the clink, won't be sporting stripes just yet though. Judge Miriam Goldman Cedarbaum stayed her sentence pending appeal. Stewart will sit down for an exclusive interview with Barbara Walters on tonight's 20/20 to discuss her future.
