It's a girl for 'Up in the Air' actress Vera Farmiga and husband, Renn Hawkey! The couple welcomed the new addition on Thursday, November 4, her rep confirmed to PEOPLE.

The baby girl, Gytta Lubov Hawkey, joins big brother Fynn who is 22 months old. Mother and baby are "happy and healthy."

Farmiga, 37, and Hawkey decided to keep the sex of the baby a surprise until delivery. "We don't know what we're having yet. I just want to have a healthy baby," Farmiga told PEOPLE earlier this year.

The actress, who filmed 'Up in the Air' two weeks after giving birth to Fynn, was set to play Gerard Butler's wife in upcoming film 'Machine Gun Preacher,' but dropped out upon learning she was pregnant. "The role would have meant traveling to Africa this summer, but because her baby is due in the fall, she would have been too far along to make the trip," a source told In Touch in April. She'll be back on the big screen opposite Jake Gyllenhaal in the thriller 'Source Code.'
