Idris Elba, is a father again.

He welcomed a baby boy Thursday with girlfriend Naiyana Garth, he tweeted.

“My Son Winston Elba was born yesterday..Truly Amazing :-)” Elba, 41, posted next to a picture of the baby holding his finger with his tiny little hands.

This is the second child for the “The Mandela: Long Walk to Freedom” actor. His daughter, Isan, was born in 2002 from a previous relationship.  And she’s just the right age to start babysitting and diaper duty.

What a strong and esteemed name Idris’ baby boy has, “Winston.” Turns out Idris’ father is named Winston, according to Wikipedia, so this moniker is so appropriate for his first male child. Congrats to the happy family!
