Demi Lovato tweeted this pic of a young Simon Cowell.
She didn't mention his age in this photo, but with the long hair and mustache, it's definitely a very young Simon.
The only thing I noticed that's the same, is the tight tee-shirt. lol
When the X Factor judge saw his photo, he tweeted back to Demi... "Someone is going to be happy sitting next to me today."
What do you think? Should Simon go back to the long hair and mustache?
