Jennifer Love Hewitt Lovely PhotoShoot: Jennifer Love Hewitt gained "It Girl" status around the days of I Know What You Did Last Summer and Can't Hardly Wait, but she's remained on the map throughout the years. The brunette beauty now stars in the TV show Ghost Whisperer, though she's better known in the media for her personal life. Hewitt has gained a reputation as a Hollywood serial dater after romancing several famous men. John Mayer and Carson Daly were two of her early loves, and she became engaged to actor Ross McCall in 2007.

Incidentally, the couple never exchanged vows. They split in early 2009, and just a couple of months later Hewitt was getting hot and heavy with her Ghost Whisperer co-star Jamie Kennedy. That relationship lasted for about a year before the duo announced they were calling it quits. Hewitt is the author of the self-help book The Day I Shot Cupid, which chronicles her dating experience.
