Macaulay Culkin still needs a little help when he's home alone.

After all, the Home Alone actor didn't know how to do laundry well until his adult years, according to fiancée Brenda Song.

"Mac is a very unique human" she shared on March 13 episode of The Jennifer Hudson Show. "Being the most famous child actor in the world, he lived and grew up in hotels. He had just never really done laundry."
