Amanda Peet

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:

Amanda Peet is pregnant again! The star and her screenwriter husband, David Benioff are expecting their second child, her rep confirmed this afternoon.

In 2007, Peet - who recently appeared in the sci-fi flick 2012 - welcomed daughter Frances "Frankie" Pen, whom she named after her mother, Penny.

Remember Amanda Peet? We didn't until this morning!Did you know she had a daughter? We reported on Frances' birth back in February 2007, though we sort of forgot about it until this morning.

That's when we came across Cookie magazine. We haven't the slightest clue about what Cookie magazine is, or why Amanda Peet is featured in it. But celebrity baby fans can't deny that she and Frances are darn cute...

Actress Amanda Peet, who welcomed her first child, daughter Frances Pen (named for her mom, Penny) in February, is feeling the rigors of new parenthood.

It's been quite the week for celebrity babies.

Yesterday, it was Desperate Housewives star Marcia Cross cranking out two of them! Today, we're happy to report that Studio 60 on the Sunset Strip star Amanda Peet, 35, has given birth to a baby girl.

She recently announced she is preggers, and now actress Amanda Peet is an honest woman to boot. See, TomKat? That's how it's supposed to be done.

Peet, 34, who stars in the NBC drama Studio 60 on the Sunset Strip, wed screenwriter David Benioff, 36, on Saturday at Peet's alma mater, Friends Seminary, a Quaker school in N.Y. City.

Move over, McDreamy, you aren't the only one making a baby announcement today.
