She was livin’ on a prayer!

Jon Bon Jovi’s wife Dorothea Hurley, 52, accidentally sliced her palm below her wrist with a knife while chopping veggies — prompting a frantic 911 call from her superstar hubby and a trip to the ER on Saturday, police sources told The New York Post.

Hurley was cutting an onion inside the couple’s penthouse on Mercer Street in SoHo at around 11:30 a.m. when the knife slipped and cut her left hand, causing “heavy bleeding,” police sources said.

An ambulance rushed her to Beth Israel Medical Center, where she received stitches, police sources said. She was released a few hours later.

Bon Jovi and Hurley, both New Jersey natives, celebrated their 25th- wedding anniversary on April 29.
