Amanda Peet ditched out on The Late Show with David Letterman Tuesday.

Unlike Sen. John McCain, who Letterman famously chided for ditching him on multiple occasions, we doubt he'll give Amanda a hard time for her excuse:

She went into labor early and delivered daughter Molly June Benioff!

The actress, who announced she was pregnant again in December, had been scheduled to appear on the Late Show to promote her upcoming film, Please Give, but instead late Monday she welcomed her second child.

"Mother and daughter are doing great," Peet's rep says.

Amanda Peet no longer looks like this!

Peet and screenwriter husband David Benioff. also have a 3-year-old daughter, Frances, who is especially excited to meet the family's newest addition.

"But there's been a lot of fighting going on in my household over names," she said. "Frankie is very excited. She just wants to call the baby Turtle.”

Kids. They're the best.
