Macaulay Culkin (40) is no longer the little boy he played in the Christmas movie Home Alone. The actor is now 40 years old and even a father since last week, ‘Esquire’ reports Monday.

Culkin and his girlfriend Brenda Song (33) became parents to a son last Monday. Little Dakota was born in Los Angeles and is named after Culkin’s sister who passed away in 2008. In a statement to the magazine, the couple said they were ‘over the moon’.

The actor and actress met a few years ago in Thailand on the set of the movie Changeland .
