Serial dater Jennifer Love Hewitt is writing a relationship advice book.

In The Day I Shot Cupid (to hit stores March 2010), the Ghost Whisperer star, 30, "reveals a surprisingly wicked sense of humor as she explores the new landscape of modern dating and offers up a wide range of practical tips, from text-flirting and IM-ing to what men and women really want, and how to start over after a breakup," according to a release.

Says Ellen Archer, president and publisher of Hyperion and VOICE, the company releasing the novel: "We were instantly sold on Hewitt's sassy and irreverent take on modern love and felt that her own confidence would be inspirational to women of all ages."

"I thought it was time to share the real story of what I've learned navigating the dating waters." Hewitt says in a statement from Voice publishers. "Hopefully, in addition to having a good laugh, women reading this will learn from some of my hard lessons."

Hewitt has plenty of dating experience.

She called off her engagement to Scottish actor Ross McCall in January. She's also been linked to John Mayer, Joey Lawrence and Carson Daly.

The actress has said she hopes to get engaged to her costar beau, Jamie Kennedy.

"By this time next year, if we're not planning something, then there's a situation," she said earlier this month.
