Demi Lovato and mugs are so three days ago. Now, the pop star has moved on from making fun of herself to poking fun at birthday boy (and old Camp Rock pal) Nick Jonas. Jonas turned 23 yesterday, prompting Lovato to send a Instagram birthday message that, while sweet, totally called him out on his mop of hair. "Happy bday to one of my favorite people in the whole wide world @nickjonas," the "Cool for the Summer" singer, who briefly dated Joe Jonas, wrote. "Love you brother. Look at that #jofro tho." Sure enough, the "Levels" singer is sporting quite the head of hair in the accompanying throwback photo from Camp Rock.
Big brother Joe, meanwhile, posted his own tribute to Nick. Guess who this adorable but slightly demonic-looking little boy grew up to be? Hint: Look at the hair.
