10 Hollywood Couples Cast as Relatives

Admit it: You were a little squicked out when you learned that then-19-year-old Hayden Panettiere was dating then-31-year-old Milo Ventimiglia, who played her uncle on Heroes. But they're not the only real-life couple to play relatives onscreen. Perez Hilton rounds up nine more:

• Will Arnett and Amy Poehler, who were married at the time, played sibling figure skaters in Blades of Glory.

• Michael C. Hall and Jennifer Carpenter were married while playing siblings on Dexter.
• On Lost, Carrie Preston played the mother of husband Michael Emerson's character, Ben Linus, in flashbacks.
• Lauren Graham and Peter Krause are dating, but they also play siblings on Parenthood.
