Cam came onto the scene with a great tune called Burning House followed by her song inspired by Amelia Earhart, Mayday. Now she is back with new music and performed her song Diane in the the Big D and Bubba studio.

Over the holidays, we kept seeing a commercial for the iPhone X and Apple Airbuds. It featured a couple dancing with Sam Smith singing. That song is called Palace and was written by Cam and Sam Smith. She sang back up vocals on the version, too. Watch her performance below.

I had no idea either. Here's the commercial below.

Who did it better? Cam or Sam Smith? My vote goes to Cam.

Listen to Big D and Bubba Monday through Friday mornings, 5 to 9, on 101.5 KNUE.
