On Thursday, Hill surprised country fans by joining her 47-year-old husband onstage at the Country Music Awards Festival in Nashville. After a duet, the two shared a sexy kiss.
This week, Star magazine claimed the couple was heading toward an expensive divorce, just one of many rumors that have plagued their 17-year marriage.
Talking with the country singers last year, Hill insisted to People.com that they are "absolutely not" splitting up. Faith said, "It's perplexing. I don't know why 'happy' can't be a story."
Hill and McGraw recently finished a joint residency at the Venetian Casino in Las Vegas.
They are parents to three daughters; Gracie, 16, Maggie, 14 and Audrey, 11.
