Mireille Enos has given birth to a baby boy.

The 38-year-old actress and her husband Alan Ruck welcomed their second child into the world yesterday (23.07.14) and have named him Larkin Zouey Ruck.

A representative for the couple told E! News: ''Mireille Enos, Alan Ruck and their daughter Vesper are overjoyed to announce the arrival of their son and brother, Larkin Zouey Ruck. He was born at 7:07am in Los Angeles. He weighs 7lbs 3oz.''

The 'World War Z' star and her beau - who announced they were expecting their second child in February - admit they are besotted with their new bundle of joy and believe his arrival was a ''miracle''.

They told PEOPLE.com: ''We are awestruck by the arrival of our little boy. The whole thing is a miracle.''

The couple, who got married in 2008, already have three-year-old daughter Vesper together, and the youngster previously admitted she couldn't wait to meet her new baby brother.

She said in February: ''I'm excited to meet MY baby.''

Meanwhile, Alan, 58, also has daughter Emma and son Sam with his ex-wife Claudia Stefany.
