Amanda Peet ditched David Letterman on Tuesday for a good reason: She went into labor early and delivered daughter Molly June Benioff in New York.

The actress, 38, had been scheduled to appear on the Late Show with David Letterman to promote her upcoming film, Please Give, but instead welcomed her second child with screenwriter husband David Benioff late Monday, April 19.

“Mother and daughter are doing great,” Peet’s rep tells PEOPLE.

Peet and Benioff also have a 3-year-old daughter, Frances.

Peet s film, Please Give, costarring Catherine Keener, opens in theaters April 30.
