[Demi Lovato talking about Who's That Boy]
"'Who's That Boy' is personally probably one of my favorites of the album. I recorded it with Dev and it was actually written by Ryan Tedder, who is the lead singer of OneRepublic, and he is really cool guy, we had a really great time in the studio, really funny, he's awesome, and I'm really excited to say that I've been able to work with such a talented writer and producer.''
