Singer-songwriter was on tour with Five for Fighting

Katherine Heigl, whose character's fiancee died on "Grey's Anatomy," had a scare when her real-life fiancee was involved in a bus crash over the weekend.

Musician Josh Kelley, who is currently on tour with Five for Fighting, apparently escaped with his life after he was involved in a major tour bus wreck, reports Us Weekly.

There's no word on his injuries or if his scheduled performance in St. Louis, Missouri on Friday (Oct. 27) will be canceled.

The 27-year-old Heigl and the 25-year-old Kelley only met last year, on the set of the video for Kelley's song "Only You." They were engaged in June, and have yet to set a wedding date.

In July, Kelley released his third album, "Just Say the Word," following in the footsteps of 2003's "For the Ride Home" and 2005's "Almost Honest."

Heigl plays Dr. Izzie Stevens on ABC's smash medical drama, "Grey's Anatomy." Also known for her series run on The WB's "Roswell," Heigl has also appeared on the big screen in "Bride of Chucky," "The Ringer" and the upcoming "Knocked Up."
