Carrie and Brad started hosting the CMA Awards and at this point Brad is married to Kim and Carrie is married to Mike. They're not going to stay married for long after an affair gets in the way of both of their marriages.
Carrie is going through a ruff time with Mike. they've been married for 2 years and all they do is fight anymore. the only person she turns to for support and comfort is brad. but brad also has his own problems. he is barley speaking to Kim. they only talk about the boys and that's it. but when they go to each other for support and comfort they grow closer together.
