Amanda is featured in Moviefone‘s 25 Hottest list.

Amanda Seyfried
Age: 23
Years on List: 2008, 2009
What She’s Done: The TV-turned-movie star appeared in small films like Alpha Dog and Nine Lives before breaking out in sing-a-long fashion opposite Meryl Streep in Mamma Mia!

What’s Next: This month she’s good girl to Megan Fox’s evil bloodsucker in the horror flick Jennifer’s Body. Then she has the Atom Egoyan-helmed Chloe, plus 2010′s Dear John (based on a novel by Nicholas Sparks), a film version of beloved comic-strip Marmaduke, and Letters to Juliet, opposite Gael García Bernal.

Industry Buzz: “She has goody-goody good looks that can turn vampy and threatening and erotic on a dime. She can play seductress one minute, and as she does in Jennifer’s Body, vulnerable nerd the next. Oh, and as she proved in Mamma Mia! she can sing and dance as well. A ceiling for this 24-year-old doesn’t exist.”
