Ashton Kutcher: Pretty cool stepdad. The Punk’d mastermind has tapped his stepdaughter Rumer Willis to guest-star on his production company’s ABC midseason comedy Miss/Guided, which features Judy Greer as a high school guidance counselor. The 19-year-old offspring of Demi Moore and Bruce Willis will play a troubled student who gets busted for triggering fire alarms. Speaking of those with famous family ties, Jamie Lynn Spears—a.k.a. Younger Sis of Britney—will appear in a different Miss/Guided episode as a rebellious senior who’s persuaded by Greer’s character to attend college.
