Crystal Gray, 38, of Clinton, told Anderson County sheriff's deputies her boyfriend, Lowell Turpin, 40, confronted her July 22 when he saw a picture of an unknown man on her Facebook page, The Smoking Gun reported Wednesday.
The sheriff's report said Gray explained the photo was of presumptive Republican presidential nominee Mitt Romney, but she told deputies Turpin remained angry and confronted her for communicating with friends on Facebook.
The Knoxville (Tenn.) News Sentinel reported Turpin allegedly threw Gray's laptop against a wall and punched her in the face.
Deputies said Gray gave them multiple contradictory accounts of the incident.
Turpin was charged with domestic assault and jailed in lieu of $1,000 bond.
