As Carrie Underwood pointed out, it's not every day that Miranda Lambert buys you a motorcycle. The 'Automatic' singer explains why she hooked her country friend and 'Somethin' Bad' duet partner up with a brand new ride.

"She was wanting a motorcycle and I wanted to get her something for all the work she’s put in, singing on the record, doing the performances," Lambert tells 'Good Morning America.' "I was like, 'OK, you’ve got to learn how to drive this thing. Don’t blame it on me!' She’s been practicing, so I can’t wait."

Even though Lambert admits she was intimidated to record with the 'American Idol' winner, they nailed it in their recent 2014 Billboard Music Awards performance, holding nothing back and showing the crowd what happens when two fierce country women join forces.

'Somethin' Bad' is off Lambert's new album 'Platinum,' which released June 3. And Underwood now has a pretty new bike to remember the fun times she had with Lambert, who states (and every country fan agrees), "She’s gonna look hot on that thing."
