Joe Jonas Sends His "Creepy" Brother Nick a Birthday Message on Instagram

On Wednesday, Joe Jonas took to Instagram to wish his younger sibling Nick a happy birthday. Joe, who is dating supermodel Gigi Hadid, shared a precious flashback photo of Nick, who turned 23 years old on Wednesday. "Happy birthday you creepy crazy smart talented best bud brother a dude could wish for @nickjonas," Joe wrote along with three cake emoji.

Nick later posted a childhood shot of himself holding up a toy microphone in a Mickey Mouse shirt thanking his followers for the birthday wishes, captioned, "Thanks for the birthday love everyone. Time flies." Just last month, Nick surprised Joe with a star-studded bash at the StubHub Center in LA for his big day, so we're excited to see what Joe has in store for his little brother.
