It was back in September that this video went viral with over 3 million views. It is trending yet again after being posted all over Facebook.

While a street musician was singing Aerosmith's classic "I Don’t Want To Miss A Thing" in Moscow, the legendary Steven Tyler incredibly appeared in the crowd, walked up to the singer, and started singing along.

At first, the street musician did not even realize the stranger is actually Steven Tyler himself!

See their amazing duet on the video below.
