Hewitt's big break came in Party of Five, while her movie career began with 1992's Munchie. Just five years later, the actress would be catapulted to teen stardom following the release of hit slasher I Know What You Did Last Summer, in which she starred opposite Sarah Michelle Gellar and Freddie Prinze Jr.

Aside from appearing extensively on TV and in movies, Hewitt also cultivated a successful side gig as a singer-songwriter. She released her debut album, Love Songs in 1992, followed by Let's Go Bang in 1995, her self-titled album in 1996, and BareNaked in 2002. Her 1999 single "How Do I Deal" even reached No. 59 on the Billboard Top 100.

Hewitt won Best Actress on TV at the Saturn Awards in 2007 and 2008 and found fame on the small screen once again with The Ghost Whisperer, which ran from 2005 to 2010. The Client List, which ran from 2012-2013, came next, for which Hewitt was nominated for a Golden Globe. She also starred on Criminal Minds from 2014-2015.
