The Little Mermaid actress surprised fans by only announcing she was expecting once she had actually welcomed her new bundle of joy with her boyfriend, rapper DDG.

While pictures had previously circulated of the star sporting what appeared to be a bump, she didn't address the pregnancy until sharing a photo holding her baby boy's hand, and writing: "Even though we're a few days into the new year, the greatest thing that 2023 could have done for me, was bring me my son… Welcome to the world my Halo," before aptly noting: "The world is desperate to know you."

Some pop-culture aficionados and netizens may still remember where they were the moment it was revealed that Kylie, at the time 20, was expecting her first child Stormi with then-boyfriend Travis Scott, back in September 2017.

Though the news had been leaked, she didn't confirm the pregnancy until Stormi was born in February 2018, and she subsequently wrote on Instagram: "I'm sorry for keeping you in the dark through all the assumptions. I understand you're used to me bringing you along on all my journeys," adding: "My pregnancy was one I chose not to do in front of the world. I knew for myself I needed to prepare for this role of a lifetime in the most positive, stress free, and healthy way I knew how."

Chrissy and husband John Legend have never shied away from sharing sweet clips of their family on social media – even through the heartbreak that was losing their third baby, Jack, while Chrissy was pregnant.

Though the model did share news with fans that she was expecting her third baby, daughter Esti, who was born in January 2023, she did surprise with news that the family had welcomed their fourth baby, son Wren, via surrogate five months later.

In 2023, Paris surprised fans with not one, but two babies! The Y2K icon announced in January that she had welcomed her first child with husband Carter Reum, son Phoenix Barron, via surrogacy.

She kept the news a secret from her family until little Phoenix was born, and months later in November, she did it all over again when preparing to welcome her daughter London Marilyn, whose arrival she announced on Thanksgiving.

Similar to Paris, Rebel kept news that she was expecting her first child via surrogacy a secret until her daughter, Royce Lillian, was born.

The Pitch Perfect actress announced little Royce's arrival with an adorable photo of her on Instagram posted in November 2022, and she wrote: "I can't even describe the love I have for her, she's a beautiful miracle! I am forever grateful to everyone who has been involved, (you know who you are), this has been years in the making… but particularly wanted to thank my gorgeous surrogate who carried her and birthed her with such grace and care. Thank you for helping me start my own family, it's an amazing gift."

The late actor and his wife waited until the birth of their sixth child, Jeremiah, in November 2021 to publicly announce the news. "Each child brings their own energy, their own manifestation of consciousness, their own lessons," James wrote on Instagram. "The ones we lost each gifted us with different pieces of the puzzle… leaving us that much more grateful for the ongoing master class we get to enjoy with this sweet, wise little one."
