If you grew up watching Home Alone and Richie Rich, you'd probably be in utter disbelief just like we are right now upon hearing that Macaulay Culkin is now 40!
Yup, the former child star just turned four decades old and he's reminding us all that he's no longer a kid.
In a hilarious Twitter post, Macaulay celebrated his 40th Birthday by tweeting: "Hey guys, wanna feel old? I'm 40. You're welcome." Boy, do we feel old!
He followed it up by saying: "It's my gift to the world: I make people feel old. I'm no longer a kid, that's my job." Good old Kevin McAllister never lost his sense of humor!
