The pregnancy news is the latest twist in the ongoing “Up All Night” saga at NBC.

After replacing their showrunner and changing the plot of the Lorne Michaels-produced show (Ava, played by Maya, is now unemployed after her talk show was canceled, leaving Reagan, played by Christina Applegate, also unemployed and trying to find her footing as a stay-at-home mom), execs had reportedly decided to switch the sitcom to a multi-cam, live audience format.

According to THR, the show’s scribes initially planned to write Maya’s pregnancy into Ava’s ever-changing storyline, but are now said to be seeking new jobs instead, following the exit of series star Christina Applegate, who announced she was leaving the floundering show last week.

“It’s been a great experience working on ‘Up All Night’, but the show has taken a different creative direction and I decided it was best for me to move on to other endeavors,” she said in a statement to Access Hollywood at the time. “Working with Lorne Michaels has been a dream come true and I am grateful he brought me into his TV family. I will miss the cast, producers and crew, and wish them the best always.”

Additionally, Will Arnett (who plays Christina’s “Up All Night” on-screen husband), is in high demand for new pilots from CBS’ Les Moonves and ABC, but neither Will nor Maya have been released from their NBC contracts, according to THR.

Steve Martin and wife Ann Stringfield, pictured in May 2009, recently welcomed their first child.

Mazel tov, Steve Martin! After Page Six reported (via sources) that the 67-year-old actor, author and musician recently became a first-time dad with wife Anne Stringfield, his rep confirms the happy news to Us Weekly. "We can confirm that Steve Martin and his wife are new parents and recently welcomed a child," the rep tells Us in a statement.

The once-divorced "Planes, Trains and Automobiles" actor married former New Yorker staffer Stringfield, 41, in 2007 in a surprise, private ceremony. A source told Page Six that the spouses are "thrilled" and "worked hard to have the baby."

A resolutely private star, Martin made extremely cryptic potential references to his bundle of joy to his 3.7 million followers on Twitter over the past few days. "My recent dada Tweet was admired by the artistic community," he wrote Feb. 11, also nodding to the quirky art movement. Slightly more telling? The tweet which read "Coo coo, cutsy wootsy, footsy pie."

Two days earlier, on Feb. 9, a female fan jokingly gushed, "Steve would you bear my children please? :-)" Martin's response about kids? "Can't stand 'em"

Martin has another baby to crow about this spring: An accomplished five-string banjo player, Martin has collaborated with "What I Am" singer Edie Brickell on a new album, "Love Has Come For You," which Rounder Records will release on April 23.

Alec Baldwin and wife Hilaria Thomas

Alec Baldwin and his wife Hilaria are set to welcome a new baby into the family, the actor's representative confirms to TODAY. Hilaria is pregnant with the couple's first child, due late this summer.

"It was a surprise, it was a wonderful surprise," Hilaria told "Extra," where she is a special correspondent. The couple broke the news with the program, and even explained exactly how they found out a baby was on the way.

Alec recalled: “There’s a scream I heard, which is a scream normally reserved if there’s a spider in the house, not exaggerating. Normally I will be reading a book, we're in the country, it's quiet, some time to really relax and unwind and sometimes once a month you hear 'ahhh  Alec, Alec!'  I come upstairs and there’s a spider on the wall, so then I hear that scream again, but it was not a spider."

Hilaria continued, “It was followed by 'I’m pregnant, I'm pregnant,' he runs up the stairs and I'm holding (the pregnancy test) and showing it to him.” 

“You can make as many jokes as you want, but it really is the most amazing thing, I’m lucky," Alec said of the news. As for Hilaria, she's feeling good and starting to plan for the new baby. “Now, I’m showing, it’s getting to be much more, like OMG this is actually gonna happen, now we can start the nursery, the everything, the dreaming," she told Extra.

Hilaria and Alec wed in New York in June 2012. He has one daughter, Ireland, from his previous marriage to actress Kim Basinger.

Baldwin's NBC comedy, "30 Rock," ended its seven-season run in January.

What's Channing Tatum most terrified about when it comes to his impending fatherhood?

"I mean, I don't think there's one thing that doesn't terrify you, but in the most unbelievably beautiful way," the 32-year-old "Magic Mike" star gushed. "Someone said it's really like watching your heart jump out of your body and run around, and I think that can possibly be the coolest thing that I've heard of."

As for how his pregnant wife is adjusting to her growing baby bump, Tatum said, "I mean, women just sort of turn into like animals in this sort of stage that they're in."

"Are you calling her an animal?" Mara asked.

"She's a complete animal right now!" he joked. "You can ask her, but in the most beautiful like humanistic animal-y way. You know she works out all of the time, eats right, impeccably right. She's just a machine."

See Jenna's growing baby bump!

Meanwhile, Tatum's "Side Effects" costar and father of four Jude Law has some parenting advice for the Sexiest Man Alive.

"I just warned him," Law cracked, adding, "I just said, 'Make the most of it while you can, brother.' They will break you. Sleep while you can."

Adele sports her name necklace.

What's in a name? You won't find out from Adele, at least not yet: The Grammy- and Golden Globe-winning singer is not talking about what they're calling her new baby ... but did she let it slip by accident?

The "21" singer was spotted out and about wearing a gold chain with the scripted name "Angelo" in it. Could Adele be following in the footsteps of many moms who work their babies' names into their everyday jewelry?

Britain's The Sun tabloid has quoted a source confirming the name, but admits "we're not sure of the significance." So take that for what it's worth.

For the moment, that's pretty much all there is to know. Though she has referred to him as her "little peanut," she told People magazine backstage at the Globes that, "I am not sharing his name at the moment. It is very personal to me. I am enjoying him on my own."

The "little peanut" was born in Oct. 2012.

Who says there are no secrets in Hollywood any more?

It's just the latest unexpected news for the Hollywood twosome, who got married in California on Oct. 30 in a top-secret bash, where the "Mildred Pierce" actress wore a custom Chantilly lace mermaid gown by Carolina Herrera. The British-born "Man on a Ledge" actor first met Wood in 2005, when they costarred together in Green Day's "Wake Me Up When September Ends" video. After splitting in 2006, they reunited in summer 2011 -- with Bell proposing in early 2012.

Back in November, Wood shot down false speculation that she was expecting. "Sorry to disappoint. But no baby on the way here," the "True Blood" star (once engaged to Marilyn Manson) tweeted after she was photographed touching her stomach and wearing a baggy poncho at an L.A. grocery store.

Rosie O'Donnell and her Michelle Rounds.

Rosie O'Donnell and her wife Michelle Rounds welcomed a new baby girl into the family Wednesday. O'Donnell made the announcement via an Instagram photo of herself, Rounds and their new baby with the caption, "we r thrilled to announce the arrival of r daughter Dakota - #withloveandthanks- AMEN."

It's a bright point in a difficult year for O'Donnell. She announced in October that she had suffered a heart attack in August, and that Rounds in June was diagnosed with desmoid tumors. Rounds' diagnosis was what prompted the couple, together since September 2011, to marry in a private ceremony.

"We married in private before her surgery, just the two of us," O'Donnell said at the time.

In addition to new daughter Dakota, O'Donnell has four other children -- Parker, Chelsea, Blake, and Vivienne -- who she shares with her ex Kelli Carpenter.

If your appreciation for Drew Barrymore dates back to when she was practically a baby herself in 1982's "E.T.," it's fun to see her on the cover of People magazine holding her own child.

People.com

Drew Barrymore and daughter Olive.

"It's the coolest moment of my life!" reads a quote from the actress beneath a picture of 9-week-old Olive, face to face with her new mom. The baby girl was born on Sept. 26.

Barrymore, 37, who married art consultant Will Kopelman in June, tells People no one prepared her for the responsibility she'd feel after her daughter was born. "You have the highest highs and yet you're facing the biggest fear of, 'How do I keep someone alive?'"

Barrymore admitted to Jay Leno in February that she hopes to have more children. "We'll start with one," she said. "See how it goes and if we could be so blessed ... that would be wonderful."
