Jennifer Love Hewitt Shows Off Horror Scream for 'I Still Know What You Did Last Summer' (Flashback)

Jennifer Love Hewitt chatted with ET in 1998 about the art of horror movie screaming and 'I Still Know What You Did Last Summer.' The then 19-year-old actress gave her best blood-curdling shriek mid-interview, explaining that it's 'not something that can be taught.' She also opened up about her friendship with Jamie Lee Curtis and how the 'Halloween' icon encouraged her to 'live it up' as she became a fellow 'scream queen.' Plus, Jennifer insisted that her karaoke scene wasn't meant to promote her singing career!
