Nick Jonas is no longer sweet 16 -- the Jonas Brother is celebrating his 17th birthday today! What do you think he'll do today? The Jo Bros are currently in Toronto, filming Camp Rock 2: The Final Jam, so maybe Nick will be celebrating with the cast and crew!
Fun fact: Nick may be the youngest of the Jonas Brothers trio, but he's actually not the baby of the family -- the boys have one other sibling, Frankie, who is 8 (but soon to be 9!).
Happy Birthday, Nick!
