Demi Lovato Really Understands Simon Cowell: He's A 'Grump' With A 'Heart'

Nothing gets by Demi Lovato!
Even when Simon Cowell tries to hide who he really is, she can figure it out!
And it seems he’s quite the complex character…simply hidden in black t-shirts.
LOLz!
Demi revealed to Company magazine the deep dark secret life of Simon as she said:

“He’s a grump. An old fart. But he has a heart that nobody gets to see. If he walked into this room, he’d treat everybody the same – he shakes everyone’s hand.”

Awww! What a cuddle bear!
We must admit we like him because he’s given us more and more Demi thanks to her X Factor gig with him!
Seriously, how could we not like someone who brought her and Britney Spears into our lives again with one show?!
Favorite person EVER!
