When Garth Brooks co-wrote the song 'Unanswered Prayers' 20 years ago, little did he know the song would make its way to the small screen.

The ballad about infidelity has been adapted by Lifetime in a new made-for-TV-movie 'Unanswered Prayers' (airing tonight at 9PM ET). Ben Beck (Eric Close) and wife Lorrie (Samantha Mathis) find their marriage test when he runs into his old high school flame Ava Andersson (Madchen Amick).

TV Squad spoke to Brooks and Close about turning a song into a movie and how infidelity is a bitch.

The prayers of Garth Brooks fans have been answered -- according to the Hollywood Reporter, one of his best-loved songs has become the inspiration for a Lifetime movie.

Based on 1990's 'Unanswered Prayers,' the country star's No. 1 hit about a married man who runs into an old high school flame and realizes that she "wasn't quite the angel that I remembered," the cable network has cast Eric Close ('Without a Trace') and Samantha Mathis ('The American President') as the married couple and Madchen Amick ('Twin Peaks') as the one who got away.

Last night's Idol was one of the liveliest shows in the past few weeks. Not because of the performances, but because of everybody else. First off , Whoopi and Chris Rock? When I first spotted them in the crowd, I rewinded my DVR five times to verify that it was them. On the fourth rewind, I had them pegged as impersonators...and darn good ones. But nope, it was them. How funny is it that Chris Rock & Whoopi show up on country night? They're both huge Kenny Rodgers fans, I'm sure.

And it appears that Ryan (like so many men recently) has gone the way of the beard.
