Macaulay Culkin is changing his middle name.
According to the Home Alone star, his middle name Carson is 'very Irish' and he wants fans to help pick him a new one.
He's getting fans to log onto his website BunnyEars.com and select their favourite name from a list of five.
The actor was on with Jimmy Fallon and said:
"I was staring at my passport recently and I was looking over my middle name. My current middle name is Carson".
"It's very Irish. And I thought, I should probably spruce up my name a little bit".
The five names you can choose from are Macaulay Culkin, Shark Week, TheMcRibIsBack, Publicity Stunt and Kieran, which is his brother's name.
