We couldn't believe our ears when we heard this crazy Metro Station news...

So, the Metro Station boys are releasing an 80s cover as their next single.

They're pretty rock, so what do you reckon it is?

Something by Motley Crue, Motorhead or Guns and Roses?

Well, actually Trace Cyrus and the boys are secret Wham fans and their Christmas single will be the classic swaying song Last Christmas!!

You heard it here first!

Yep, that's right, despite his tatts and piercings Trace is a big George Michael fan.

To get you excited here's clip of the original....check out that 80s hair...!

Metro Station will be on tour with Trace's sis Miley in December.

Last Christmas will be released around then.
