Julie Ann Evans of Cinderford, Gloucestershire, will stand trial in July after a court heard that she allegedly tore off her husband's ear during a dispute last year.
She admitted before the magistrates that she poured water over her sleeping husband James, threw toast at him, and rubbed butter in his face.
Julie, however, has denied almost tearing his ear off, which required 13 stitches, The Citizen reported.
"She was married to James Evans and they are now divorced. He came home from work after being away and he needed to work from home but his wife kept asking him to do things for her," prosecutor Theresa Perry was quoted by the daily as saying.

"The next morning she started an argument and threw her toast at him. He left, as he felt she was being petty. She grabbed a handful of butter and smeared it over his face. He tried to rub some of it back on her. She is alleged to have cut his ear during the struggle which allegedly followed," Perry said.
At Cheltenham Magistrates' Court on Tuesday, Julie initially admitted two charges of common assault, committed on July 12 and 13, 2013.
"I am going to invite the Crown to have a look at it. It is something I am going to keep an eye on," Bopa-Rai said.
To the fresh charge of assault occasioning actual bodily harm, Julie Evans pleaded not guilty and there will be a trial over that matter later this year.
