Baby Watch

Due early next year, Jenna is carrying two little ones inside her.

Former child star Mayim Bialik has a three-year-old son and was due with her second child in the fall. While no one has reported if she had the baby yet, the 32-year-old turned up at an L.A. farmer's market this weekend wearing a librarian chic skirt, sensible shoes, trendy ankle bandage and -- voila! -- a newborn slung across her chest. Whoa!

To control birth rates, Maasai pastoralists in the Great Rift Valley of Kenya place a leather contraption called an olor on a billy goat to block its genitals from mounting the nanny goat.

Casey Aldridge and Levi Johnston could learn a thing or two from animal husbandry.

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.

Charlie Sheen and Brooke Mueller are taking that whole "Two and a Half Men" thing to heart.

Our sources say Brooke is double the preggers -- as in she's expecting twins. Your move, Denise.

The little tykes would be the first for Brooke; Charlie has two young kids with ex Denise Richards and a 22-year-old daughter named Cassandra he had out of wedlock with girlfriend Paula Profit.

Three-month-old Maddie Briann Aldridge is gonna have to wait to have a lil' baby brother or sister, because Jamie Lynn Spears is not pregnant, y'all!

While several reports are claiming Jamie Lynn is preggers again, an unimpeachable source tells TMZ Britney's baby sis does not have another bun in the oven.

Contrary to popular belief, it is safe for a healthy pregnant woman to fly. On the other hand, lip-synching can ruin you.

Take a look at this video. The pappers thought the woman flanked by LAX police was Jamie Lynn Spears, who flew in yesterday on Delta. Now here's where the plot thickens.

Law enforcement sources tell TMZ that, on Tuesday, someone from Britney Spears' camp contacted LAX police, asking for a security escort. The way the cops understood the call, Britney was flying in Wednesday with Jamie Lynn, her baby and Lynne.

At the last minute, cops found out Britney was not on the plane. They still were sympathetic because a bunch of pappers were at the airport waiting for Jamie Lynn. Cops were concerned her baby might be at risk in a pap crush, so they allowed Jamie Lynn and crew to exit the plane onto the tarmac, where a car drove them away.

Now here's where it gets good. For some reason, the cops wanted to fool the paparazzi, so they got a random woman on that flight who kinda sorta looked like Jamie Lynn and asked her if they could escort her to baggage claim. She said yes, and the ruse began.

The 39-year-old showed off her latest maternity accessory while wearing 3D glasses in NYC on Thursday.

In lieu of a tramp stamp, Bristol Palin went with the more traditional unwed pregnant teen engagement ring.

Sources close to Jamie Lynn Spears say she completely sympathizes with 17-year-old Bristol Palin -- and JL has some unwed teen mother advice for her preggo peer.

We're told Jamie Lynn thinks Bristol needs to stay strong and be an example for young moms everywhere. Jamie also wants Bristol to be aware everyone is shining a spotlight on her right now, so it's important she remain as positive as her EPT!

Take that, Internet conspiracy theorists!

Sarah Palin's 17-year-old daughter is pregnant, it was announced today, and she plans on keeping the child and marrying the baby daddy. Jamie Lynn Spears, is that you?

Palin has been dodging rumors the child she had back in April wasn't hers -- but rather her daughter's.
