Imagine if they released a single!!
***UPDATE: Check out the FULL video release below.
Ed Sheeran and Prince Harry have teamed up for a great cause and told us all about it.
Keep your eye on the Sussex Royal Instagram page because Prince Harry has teased a collaboration with Ed for World Mental Health day which should drop later today.
Ed rocked up at 'Frogmore cottage' with a camera crew, rang the doorbell and then this happened.
PS. the doorbell chime of God Save the Queen is everything.
And how is Prince Harry's line... "It's like looking in a mirror!"
And here it is... the full video release, as promised by Ed and Harry! Our two favourite red-heads.
