The girl was born Dec. 18 at a hospital in Chicago, the comedian’s hometown.

Locklyn Kyla Vaughn weighed 7 pounds and measured 20 inches at birth. The actor’s rep confirmed the news to People.

“Both of them couldn’t be happier to welcome their sweet little girl into their family!” said a friend of Vaughn and his wife.
