Carrie Underwood Says Her Marriage Is Good While 'Everyone Is Getting Divorced'

Carrie Underwood reveals the secret to her great relationship with husband Mike Fisher.

Despite a summer full of celebrity heartbreak, Carrie Underwood's marriage to her husband, Mike Fisher, couldn't be stronger.

The 32-year-old country singer covers Cosmopolitan's December issue, and reveals why she and the 35-year-old NHL pro have such a solid relationship.

"Everyone is getting divorced," Carrie acknowledges. "They're dropping like flies! But we are good. It helped that we were both established before we were married. Neither one of us could be like, 'I didn't know it would be like this!'"

Carrie and Mike married in July 2010, after first meeting at one of her concerts in 2008. The two welcomed their first child together, Isaiah Michael Fisher, in February.

Still, Carrie did have a few failed relationships before marrying Mike. Most notably, she dated Dallas Cowboys quarterback Tony Romo in 2007, and actor Chace Crawford in 2008. She channels her past heartbreak in her music, and much like Beyonce and her Sasha Fierce alter ego, the "Before He Cheats" singer says she definitely has two sides to her.

"When I am onstage, I am not Carrie: I am Carrie Underwood," she explains. "Obviously, I would never run off to Vegas and get drunk and marry a guy or trash some guy’s car. But everybody has had somebody who's cheated on them or some jerk they dated."

ET caught up with Carrie in June at the 2015 CMT Awards, when she revealed the secret to her incredible post-baby body.

"I was healthy throughout my pregnancy -- as healthy as I could be. I definitely splurged more than usual, but I just started getting back into it afterwards," she said. "I make workouts happen wherever they need to happen. [Isaiah] falls asleep ... and I'll just go do [a workout] real quick!"
