Baby Watch

In typical Alba fashion, she did her best to shield her face from cameras after leaving an L.A. gym on Tuesday -- but there was no hiding Jess' growing fetal love handles.

TMZ has learned that a 22-year-old Playboy Playmate is claiming that David Spade is the father of her unborn child. Holy Jamie Lynn!

Jillian Grace, Miss March 2005, is alleging that she had a relationship with the comedian, resulting in her becoming pregnant. Grace was discovered by Playboy after posing for test shots on the Howard Stern show.

Spade tells TMZ, "I had a brief relationship with Jillian Grace. If it is true that I am the father of her child, then I will accept responsibility."

Oh, baby! Both Nicole Richie and Christina Aguilera are in labor! Boil some water!

Us is reporting that the "Simple Life" star has checked in and will soon deliver her bundle of joy, and TMZ has just spotted grandpappy Lionel, uncle-to-be Benji and his fiancee Sophie Monk at the hospital. Getting the band back together!

Multiple sources have confirmed to us that Christina is there too. Maybe they can share a room?!

Cash Warren's usually dour baby mama looked spectacular yesterday at the Glamour Magazine V Day Luncheon, showing off her great rack ... and surprisingly, a rare smile.

Former "Bachelorette" Trista Rehn ('memba her?!) and her chosen hunkband Ryan Sutter showed off their 5-month-old son Maxwell -- and their ripped bods -- on the beach in Hawaii on Thursday. Say cheese!

You couldn't cast a better looking family pic if you tried.

TMZ has learned ex-"Idol" Jessica Sierra spent New Year's Eve in a hospital bed after a serious pregnancy scare.

We're told Sierra was rushed from her jail cell in Tampa, Fla. to Brandon Regional Hospital. Jail staff feared she might lose her baby. A source tells us that Sierra was suffering from "severe bleeding." She and the baby are okay.

Sierra is in the slammer after battery and cocaine bust. The judge is springing her loose tomorrow and she will be transported to the Pasadena Recovery Center to spend the next year in rehab.

Nicole's shirt and jacket hid any noticeable baby signs.

So let's review. Nicole and Tom didn't get pregnant during their 10 year run. Some speculated Tom was firing blanks, but now he's had a kid. Some thought she couldn't get pregnant but now she is. So what was the deal? Sounds like a good one for user comments.

While unwed pregnancies are all the rage in Hollywood, Nicole Kidman's reps have confirmed that the married waxen star is going to have a baby. Birth!

A playmate for Suri! Miss Kidman also has two others -- Scientolokids with Katie Holmes' first husband.

Nic's current husband is country singer and rehab grad, Keith Urban. Perhaps, this child will grow up to call Nicole "mom."

Gyllenhaal's relationship with Reese Witherspoon appears to be getting more serious, as Jake was snapped at a Malibu park -- with Reese, her mini-me daughter Ava and carrying Ryan & Reese's son Deacon on his shoulders. Brokeback stepdad - is that you?!?

Out in public and wearing matching hats, this Gyllenspoon collaboration is already a bigger hit than "Rendition."

TMZ caught Larry shielding his daughter from the cameras at the airport as he brought her to their waiting SUV, then doubling back to the baggage claim to collect an obscene amount of luggage from the terminal. According to Larry, the bags were Dannielynn's, full of "presents she racked up" from Santa.

Someone's been a good girl this year!

Nicole's rep tells news.com.au, "She's in Australia making a film and her family are in Australia. She's happily ensconced away somewhere having a few days break. It's the silly season. As far as we're concerned, it's another rumour out of London."

A Daily Mail report claiming Kidman was expecting had widely circulated. Apparently, the only thing she should be expecting is a retraction!

The soon-to-be baby mama, 22, was all smiles as thousands of shoppers burst into one of the world's largest department stores to celebrate the holidays the right way -- by spending tons of dough on quality goods at discount prices!

Mother of three Shanna Moakler, 32, is not shocked about 16-year-old Jamie Lynn Spears' pregnancy -- and she's got the stats to back her up!

The potentially single mom (who can keep up with her and Travis' roller coaster relationship?) -- blogged on her MySpace today about the preggo teen, asking why anyone was shocked about Britney's sister.

She rambled on with stats about teen pregnancy, abortions and miscarriages ... did you know about one million teens become pregnant each year? When "Crowned" is over, perhaps Shanna should consider a career as a high school Health teacher!

TMZ caught the ever-silent, never-smiling Alba leaving Emerson Hall Fitness, a "Zen Fitness Training" workout zone in West Hollywood yesterday afternoon.

Alba wasn't looking too Zen on her way out though -- showing off her somewhat growing belly but hiding her moneymaker of a face as she took off.
