Carrie makes Miranda nervous…like first date nervous.
Well, this sure isn't how I thought it woulda' went down. I thought Miranda and Carrie were having a girls night, painting eachother's toes, sippin' on wine and telling stories about Blake and Mike and then all of the sudden mutually agreed to do a song together….turns out…I was wrong.
Miranda told PEOPLE: "To me, this is such a big deal that Carrie and I are singing together," Lambert, 30, tells PEOPLE Country. "It took me forever to write the email to ask her, like I was writing to someone I had a crush on and you don't want to mess it up."
