In her preteen years, Biel landed her very first acting job as minister's daughter Mary Camden on the WB family friendly series 7th Heaven. Growing up in front of the cameras, she faced a tough transition from ingénue to respected actress. She made the choice to pose scantily for a men's magazine at age 17, hoping to distance herself from her character's goody-goody image. She left 7th Heaven with the promise of returning to make occasional appearances. Free to take on more mature roles, she buffed up for parts in horror and action movies such as 2003's The Texas Chainsaw Massacre, 2004's Blade: Trinity and 2005's Stealth. She also used her much- admired comeliness to beguile on the silver screen in love interest parts in 2006's The Illusionist, 2007's I Now Pronounce You Chuck and Larry and 2008's Easy Virtue. Off screen, Biel supports numerous charities and romances boyfriend Justin Timberlake.
