When two of country's biggest ladies get together to record one song, it can be a whole lot of fun. Carrie Underwood and Miranda Lambert released a behind-the-scenes video that showcases the good times that were had while recording 'Somethin' Bad.'

The two blondes are both shown singing their hearts out at their mics while recording. Lambert opted for a plaid shirt and jeans to stay comfy while in the studio, and Underwood went for ripped jeans and a grey T-shirt. Lambert kept the energy high, especially when she was goofing off while the background vocals chant "Hey!"

The pair sang together, making notes and practicing before getting behind the big microphones. Their harmonies were shown as being recorded separately, but the two voices come together like a happy marriage.

A full band was brought into the studio to record the single. The girls kept their toes tapping on the hardwood floor while they belted out their notes. During downtime, they had visitors at the studio and sat around a black leather sofa enjoying each other's company.

The finished recording of the song was definitely not 'Somethin' Bad.' The single appears on Lambert's newest album, 'Automatic.' The duet was first performed live at the Billboard Music Awards in May, and then the pair of country's biggest superstars brought the song to the CMT Music Awards and CMA Fest. Hopefully, a music video for the single is next.
