Demi Lovato is full of praise for Frankie Jonas

Move over Joe Jonas, it looks like your little brother Frankie is the one who impresses Demi Lovato the most.

Nine-year-old Frankie has just made his acting debut in Camp Rock 2, which also stars his brothers Joe, Kevin and Nick, as well as Demi.

“He’s the biggest rock star of all of them.” Demi said of little Frankie.

“He’s got swag like Justin Bieber and he rocks out like Mick Jagger, so he’s kind of a combination of the two. He’s kind of like the ultimate rock star.”

“Watch out, Justin Timberlake!”
