'Home Alone' star Macaulay Culkin turns 40, says making people feel old is his job

In most people's eyes, American actor Macaulay Culkin will forever be that little kid in the classic film franchise "Home Alone." 

But today, he had great pleasure in reminding the world that he has, in fact, just turned 40 years old.

On Twitter, the former child star said, "Hey guys, wanna feel old? I'm 40. You're welcome."

"It's my gift to the world: I make people feel old. I'm no longer a kid, that's my job," he added.

His initial tweet already has almost 700,000 likes, just two hours after he posted it.

He also joked that he's at the right age to start his midlife crisis.

"Since I'm 40 I think it's about time to start my midlife crisis. I'm thinking of picking up surfing. Do you all have any suggestions?" he wrote.

Culkin turned 40 on August 26.

In "Home Alone" (1990), he played eight-year-old Kevin who was accidentally left behind when his family leaves for France, and found himself defending their house from burglars. He returned to reprise his role for "Home Alone 2: Lost in New York" (1992). —JCB, GMA News
