"She's a very complex individual -- kind of a tough girl, bad ass," Rimes tells Music City TV. "She falls in love with a new guy in town."
There's no word yet on the actor who will portray this new guy, but Rimes reports there will be a love scene between the two.
"I definitely will be making out with someone," she says. "I think I know who but I can't say yet."
So what does hubby Dean Sheremet think of his wife kissing someone else? He's nothing but supportive.
"I said, 'If you look awkward, it's gonna look even worse,'" Sheremet says. "I said, 'You better go for it.' It doesn't bother me. I'm a very confident person!"
The movie begins filming in November in Calgary, Canada.
