Celebrity Baby Birth Announcements

A flash of a teeny-tiny foot. A photo collage. A shout-it-from-the-rooftops tweet. Even celebrities aren't immune to the excitement of finally seeing a brand-new baby after nine long months. From Ashton Kutcher to Zoe Saldana, here are the adorable ways some A-list parents have announced the arrival of their little love nugget -- whether through Twitter, Facebook, or Instagram.

One (more) kid and counting! The fourth-oldest child in the Duggar family gave birth to the fourth Duggar grandchild on April 6, 2015. Jill and her husband, Derick, chose a biblical name for their first child. Jill shared two photos on Instagram, along with the captions: "He's a beautiful baby boy! Israel David Dillard, born last night at 11:49pm!" and "So thankful to God for this handsome little guy! 9lbs 10oz, 23 inches long! #IsraelDavidDillard #babydilly."

After giving birth in February 2015, the country star took to all her social media pages to share an adorable first peek of her newborn. She shared, "Tiny hands and tiny feet? God has blessed us with an amazing gift! Isaiah Michael Fisher -- born on February 27. Welcome to the world, sweet angel!"

The low-key actors welcomed daughter Wyatt on October 1, 2014, and the very next day gave eager fans the ultimate riddle: to guess which baby was their little girl out of eight photos. Thankfully, it took the sleuths at TMZ just one day to figure out the answer.

Leave it to Hollywood's most charming couple to come up with a playful way to announce baby number two's birth on December 19, 2014. After daughter Delta Bell was born, Dax tweeted that though the baby didn't look like either parent, "we're going to keep her anyway." Kristen's own tweeted response? A photo of a primate parent and baby holding hands, and an affectionate warning to Shepard that "the estrogen has now hit critical mass" in their home. Adorable.

She may have kept mum on what day she delivered her twin boys, but Zoe Saldana wasn't shy about spreading the happy news with fans. On January 2, 2015, the Avatar star tweeted that she was "starting our #NewYear with a full house. Our boys are finally here!" and also posted a sweet pic on Instagram of two bottles and two pacis.

A proud mom of two, Shakira first announced the birth of her second son, Sasha, on her website. But she didn't take much time before showing him off -- less than a week, to be exact. She posted a precious Instagram snap of the babe's wee foot on February 3, along with the caption, "I have Daddy's feet, it looks like I've been playing football my whole life."

Personal website? Check. Twitter? Check. Instagram? Check. When baby Brooklyn Elisabeth arrived in January, Vanessa Lachey didn't leave a social media stone unturned when sharing the news. Just in case the heartfelt caption didn't melt your heart ("we are over the moon," she wrote), she also posted a beautiful black-and-white close-up of the two holding hands.

"The greatest thing on the planet." That's how new mom Kelly Clarkson described daughter River Rose in a sweet baby-reveal Instagram post on June 20, 2014. And in true diva fashion, the one-week-old tot's first public photo was nothing short of perfection.

We didn't think it was possible for Alicia Keys and hubby Swizz Beatz to outdo their stunning pregnancy announcement. But that's exactly what they did when baby Genesis arrived in December 2014. The couple sent out identical, adorable messages full of emojis and rhymes, writing, "The joy of joy is joy!! It's a boy! We are so grateful! #blessings!!"

Another beauty was welcomed into the world when supermodel Coco Rocha gave birth on March 28, 2015 to Ioni James Conran. Rocha and her husband, James Conran, shared their happy news on all the usual social media sites -- along with an abundance of adorable photos. The couple even created Ioni's first Instagram account (@ioniconran) -- and now she has even more followers than her daddy!

Almost as soon as baby Axl was born in September 2014, new parents Fergie and Josh Duhamel started posting photos of their ridiculously photogenic tot. The Black Eyed Peas mom wrote, "Axl Jack Duhamel Day 1 Life is good :) #paparazziyoucanleaveourhousenow"

Prince George's July 2013 birth announcement was regal with a capital R. Shortly after making his tardy debut, a press released confirming his arrival was issued to anxious media outlets around the world. Then, keeping with royal tradition, an official announcement was propped up on an easel outside of Buckingham Palace for the public to ooh and ahh over. The next day, the happy family walked out of St. Mary's Hospital in West London and presented the future king to a sea of photographers and well-wishers.

When your mom is a Destiny's Child, having just one birth announcement simply won't do. In fact, baby Titus had four to declare his November 2014 arrival: an Instagram shout-out from Aunt Bey and three Facebook posts from Rowland, including a shot of the babe's sweet feet and a lullaby specially written for him.

The powerhouse diva went all-out in celebrating her second pregnancy: a nude baby bump magazine cover and a, um, baby shower cake shaped like a woman giving birth...on a rug. So it was surprising when her tweeted announcement was tame ("So proud to welcome our beautiful daughter Summer Rain Rutler into the world."). Aguilera also waited five months before revealing the first photo of her Lil' Diva, which is too cute not to share: Watch out...another one's getting ready to conquer the world! #driven #diva2

If you have Ryan Seacrest on speed dial and an E! film crew recording your every move, do you really need to announce a baby's birth yourself? For baby number three, Kourtney Kardashian decided to do the honors herself by posting a cute Instagram pic of Mom and Baby holding hands. "Madly in love with my little Reign Aston Disick," she wrote on December 21, 2014.

They may be megastars, but Emily Blunt and John Krasinki chose a refreshingly straightforward way to announce daughter Hazel's birth. In February 2014, the first-time dad tweeted, "Wanted to let the news out directly. Emily and I are so incredibly happy to welcome our daughter Hazel into the world today! Happy bday!" Three months later, he (finally!) tweeted a pic of his adorable kiddo.

K-Cav isn't known for being understated (see: any episode of Laguna Beach or The Hills), but we've got to hand it to the mom of two for the subtle way she introduced son Jaxon Wyatt. She gave fans a first glimpse of the then-2-month-old on her eponymous app and casually mentioned, "Speaking of Jax, here is my precious little peanut..."

Lucky magazine editor-in-chief and social media darling Eva Chen cribbed the most famous line from Scarface to announce her baby girl's birth on Instagram: "Say hello to my little Ren!" If that weren't cool enough, the trendsetting mom and baby were dressed in color-coordinated outfits. #mommychic

Let's be honest: Winnie Rose had us in the palm of her hand long before we spotted her and dad Jimmy Fallon wearing matching bee outfits. Considering how adorable she was right after her July 2013 birth (exhibit A: Fallon's Instagram pic), can you blame us? And the proud papa also showed off an equally-adorable first photo of his second baby, daughter Franny, a few months after her birth.

When it came time to tell the world that baby number two had arrived, the 7th Heaven star let her 2-year-old daughter, Kenzie, do most of the talking. The actress shared a touching Instagram photo of the siblings with the caption, "Kenzie is proud to announce the arrival of her sweet baby brother, Hutton! Thank you for all the love and well wishes!"

When daughter Avri Roel was born November 5, Robert Downey Jr. took to Twitter and Facebook to spread the news. And his posts were exactly what we'd expect from the witty Avengers star. After tweeting "girl joy!" he wrote on Facebook: "After 9 months of intensive development, Team Downey is pleased to announce our 2014 fall/winter project. Principal photography commenced 11-14 and will continue until she says, 'Dad! You are embarrassing me...I'm 30, this has gotta stop.'" He also promised to post photos "when I'm not too busy staring."

The Russian model took to Instagram in May 2014 to deliver the news about baby Maxim's birth. But instead of a simple selfie, the blonde bombshell posted an artful shot of herself and husband Antoine Arnault holding their kiddo's tootsie.

Perpetual grump Simon Cowell had reason to smile when son Eric was born in February 2014 -- and he (shockingly) wasn't afraid to show it. A mere two days after the cutie pie made his debut, the world got its first glimpse of him cuddled up with his beaming parents. "I never knew how much love and pride I would feel," Cowell tweeted.
