On Wednesday, Joe Jonas took to Instagram [2] to wish his younger sibling Nick a happy birthday. Joe, who is dating supermodel Gigi Hadid [3], shared a precious flashback photo [4] 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 [6] 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 [7] 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.
