Max Greenfield and Tess Sanchez Welcome Son Ozzie James Greenfield—Get Exclusive Details on Their Baby Boy!

Actor and his casting executive wife are already parents to a daughter named Lilly

There's a new little boy in a New Girl star's life!

Golden Globe-nominated actor Max Greenfield and his wife, casting executive Tess Sanchez, welcomed son Ozzie James Greenfield Monday, the couple tells E! News exclusively. Sanchez announced her second pregnancy in April. Little Ozzie weighted 6 lbs., 12 oz. and joins big sister Lilly Greenfield, who was born in 2010.

A source tells E! News everyone is "doing great" after Ozzie's arrival.

Needless to say, it's been a busy summer for Greenfield and his wife.

In addition to reprising his role on Schmidt on Fox's New Girl, Greenfield will appear on FX's American Horror Story: Hotel sometime this year. To prepare for the role, the actor underwent a total physical transformation. "He plays an addict who checks into the hotel and tangles with Sarah Paulson," series creator Ryan Murphy said.

"He cut off his beautiful hair and dyed it and then we had to let the roots grow in," he told E! News just weeks ago. "I think he's lost 30 lbs., which is odd because his wife is due to have a baby any day now, so she's nine months pregnant and he's living on celery water. She's not happy about that. Yesterday I talked to him and his waist is down to, I think, a 27. He's really committed to it, and he looks amazing."

American Horror Story: Hotel debuts Oct. 7 on FX.

Fox renewed New Girl for a fifth season; a premiere date has not been announced.
