Serial monogamist Jennifer Love Hewitt thinks she has enough experience in the dating department to come to the aid of the rest of us. After a failed relationship with John Mayer and broken engagements to Carson Daly and Ross McCall, Love Hewitt is pressuring her current beau to popping the question -- and dishing out advice to single ladies. According to People, the actress is putting out a book titled The Day I Shot Cupid, which will address relationship topics like flirting via text and how to start over after a breakup.

While it's true she has dated her fair share, we're not sure Love has the know-how to help us recover from ill-advised late night sexting, first-date mishaps, and horrifying breakups. Just because you're famous, doesn't mean you know what you're doing. But that little fact hasn't stopped her or other stars from counseling us on their various subjects of expertise.
