Hewitt was born on February 21, 1979, in Waco, Texas, to Patricia Mae (née Shipp), a speech-language pathologist, and Herbert Daniel Hewitt, a medical technician.

Hewitt grew up in Nolanville, in Central Texas, and has close kinship ties in parts of Arkansas. Hewitt received her middle name after her mother promised her college friend (named "Love") that if she had a daughter, she would name the girl after her.
