Paramedics responded to the home of Amy Poehler and Will Arnett yesterday.


It happened in L.A. According to the photo agency the call may have been for Amy's mother.

Amy and Will had a son three months ago, but apparently the call did not involve him.

One month after giving birth to son Archie, Amy Poehler takes a stroll through the West Village with her little not-ready-for-prime time player.

"Please don't leave 'SNL,' mommy. Please!"

Sources tell TMZ Amy Poehler has been in labor all day and just had a baby boy.

Obviously, Amy will not perform on "Saturday Night Live" tonight.

We're told Seth Meyers will do Weekend Update all by his lonesome, but there's no word on whether her "Bronx Beat" skit with returning cast member Maya Rudolph -- who will be playing Michelle Obama tonight -- has been totally scrapped or not.

Amy Poehler screamed "I'm a Red Sox fan!" to shocked Yankee supporters yesterday in New York -- at least she was in the safety of her car!

Also in NY: Natalie Portman walked a dog that didn't piss all over her, Steve Guttenberg was in need of a hot hookup, Jason Lewis swapped spit with our photog and Mariah Carey was her usual diva self.

In L.A.: Lindsay Lohan dodged questions about her slip from sobriety, P!nk was out in Malibu with her new dude, Paula Abdul ate out with Simon's girlfriend, Simon dined elsewhere, Reese Witherspoon was boxed in by the paps and Denise Richards thought our camera was actually filming her for her reality show.

Unlike her debates with Barack, Hillary Clinton's appearance on "SNL" this weekend came with no arguments from the New York senator.

Sources tell TMZ the skit -- featuring Amy Poehler in Hillary drag -- was written on Saturday afternoon and sent over to Hill's camp for approval. We're told the material was promptly okayed with no edits. She's not the candidate for change!

While sources tell us Clinton skipped the earlier run-through, she showed up to the studio at around 10 p.m. -- blanketed with over 15 security guards and Secret Service. We're told Hillary was a really good sport and left not too long after the opening sketch was finished.

After Tuesday's primaries, the country may know if her campaign is finished.

How do you like your birthday blonde? Funny like Amy Poehler, 36, or hot like Heidi Montag, 21?

The question is ...

Rail thin Kate Bosworth and a healthier looking Julia Stiles were rocking similar Daisy Duke shirts in NYC yesterday -- with Stiles winning the look by not pairing it with awful jeans and equally wrong sunglasses. Also in New York: still funny "SNL" cast member Amy Poehler and a thumbs-up Kanye West.


Back in L.A., Justin Timberlake's girl, Jessica Biel, hid from cameras, Jack Osbourne kept his Geico caveman look going, Jon Lovitz acted like a statue on Sunset, and a hooded Ja-Rule hit up Area. A fresh-faced Felicity Huffman, "Bones" hottie David Boreanaz, "Heroes" sidekick James Kyson Lee, and Cheryl Hines were all at the Clothes Off Our Back event hosted by a fake jewelry wearing Jane Kaczmarek.

All this and more in today's rodeo-to-Rodeo edition of Star Catcher.
