County singers Carrie Underwood and Miranda Lambert aren't the only ones bonding from their Somethin' Bad collaboration. According to Underwood, their husbands have been developing a friendship of their own.

The good humor between Underwood and Lambert has been of public interest ever since Lambert bought Underwood a motorcycle as a "thank you" gift for singing on her latest album, Platinum. "It was a lot of fun being in the studio with her," explained Underwood in a recent Access Hollywood interview (featured below).

While Underwood and Lambert's friendship strengthened in the recording studio, CMT took a closer look at their husbands, who apparently hit it off at the ACMs.

"During the ACMs, we actually hung out quite a bit because we were there for a few days," said Underwood, "and our husbands got to talk. I think there's a bit of a bromance going on."

Lambert's husband of three years, fellow country artist Blake Shelton, is no stranger to the bromance. Some might even say he has the market cornered and even Underwood admitted that the musician has "a lot of bromances going on." Underwood has been married to NHL player Mike Fisher since 2010.

With both couples tied down by incredibly busy schedules, it's unlikely that they have a lot of time to hang out together off the road, but with social media and the public spotlight, it will be easy for fans to see how this budding "bromance" develops.
