The 'Gotham' co-stars have revealed that their daughter, Frances Laiz Setta Schenkkan. was born on March 2.

Representatives for the pair told USA Today: "Morena and Ben are so happy to welcome baby girl Frances Laiz Setta Schenkkan on March 2. All are happy and healthy and appreciate the well-wishes."

The couple's 'Gotham' characters, James Gordon and Dr. Leslie Thompkins, are also expecting a baby together on-screen with Morena explaining that it was "a total coincidence".

She said: They were already planning on doing that with (our) characters when I got pregnant. When I told them they were like, 'Okay, great!' and I was like, 'What?' It worked out perfectly."

Frances is 37-year-old Ben's first child but Morena, 36, already has a two-year-old son, Julian, with her estranged husband, Austin Chick, and while she has primary custody, Morena has been ordered to pay her ex $23,000 a month in support.

Morena recently said: "I understand people are curious, but it doesn't matter. My personal life is my personal life. All I think about is my son, my family and my future family.

"He's going to be of an age where he can go online and look at everything that's been said and done. What I say is the only thing I can control.

"I just want him to know that he's loved and there's the story that people tell and the story that mom tells, and he'll know what's true. That's all that matters."
