U.S. recording artist Kimberley Locke says she is engaged to high school sweetheart Don Campbell, her publicist said Tuesday.

Originally from Gallatin, Tenn., she has dated Campbell, of Jackson, Tenn., on and off for 10 years. No date has been set for the wedding.

Locke rose to fame when she was named the second runner-up on season two of the Fox TV series, "American Idol."

She scored a hit with her song, "8th World Wonder."
