Miranda Lambert's latest single, 'Little Red Wagon,' from her No. 1 'Platinum' album, was written by songwriter Audra Mae, who included it on her 2012 'Audra Mae & the Almighty Sound' record, never dreaming that the five-time CMA Female Vocalist of the Year would want to record the song as well.

"Apparently somebody she was on the road with had heard my record and suggested the song to her," Mae recalls to ETOnline. "They started listening to it, and she really liked it. She is one of the most grounded, humble people you'll ever meet, also a Texas girl."

Lambert might be one of the most famous faces in country music, but apparently she still gets starstruck when she comes across true talent.

"She was apparently nervous about contacting me, so her husband [Blake Shelton] cornered my publisher at a country awards show in Vegas and said, 'Can you please get me her number because my wife has listened to this record all the time, and she's too shy to do anything about it,'" Mae recalls. "She hit me up and invited me to a party they were having for the finale of 'The Voice,' and so that was the first time I met her."

The two women reunited a few months later, and Lambert graciously asked if she could play 'Little Red Wagon' for Mae, to get her feedback and approval.

"I thought it was so funny because that's not common at all," Mae says. "It's really not necessary, especially if you're a huge artist -- you can do whatever you want! But she's old-school cool."

Now that Mae has gotten to hang out with Lambert and Shelton, she has become not only a fan, but also a friend.

"I can't say enough good things about the both of them," she says. "They're real, they're not just playing the game. It's not an act, it's really important that people know that about them."

Mae is on a songwriting streak lately. She also co-wrote Kelly Clarkson's brand-new single, 'Heartbeat Song,' and is working with the Band Perry on their new album as well.
