Demi Lovato did a great job as the host of the 2012 Teen Choice awards! It was awesome seeing her do her thing through a ton of makeup and wardrobe changes. As her co-host Kevin McHale said: "I just want to point out how hot Demi looks. Can we give it up for that?"

She DID look great, but I have to say, her megawatt smile was what made her such a great host. Demi miust've been having a great time, because she took the big responsibility in stride. I'm sure it didn't hurt that some of her best friends were around for support, including birthday girl Selena Gomez!

In fact, there was even an adorable and impromptu celebration for the birthday girl she and her band were awarded the Choice Pop Band award. 

Here are a few other highlights from the evening:
