Super producer Timbaland has posted a video online praising teen Disney star Demi Lovato. 

Lovato, who has recently been in rehab to deal with 'emotional and physical issues', often flitted between actress and singer, and now with the backing of the 'Just The Way You Are' hit maker could have an even bigger career ahead of her when she returns to the public eye. 

In the video Timbaland says:

"Demi, I'm so... I'm sitting here looking man I'm just like 'wow'. You're so amazing girl, I'm like, I'm kind of funny about, very hard to please. I'm just not an easy person to please. I'm very impressed."
