Kate Upton's very casual pregnancy announcement

It's no Beyonce with all the flowers, but it's still special.

Kate Upton just shared some very exciting pregnancy news in a very chilled manner on her Instagram account on Saturday morning.

Underneath a photo of herself in a red suit, hands in her pocket, the supermodel captioned the pic with the simple hashtag "#PregnantinMiami". She also tagged her husband, baseball player, Justin Verlander.

Now, by celebrity baby announcement standards this was a very relaxed way of relaying the news but nonetheless, fans and celebrity friends started sharing messages of congrats right away.

Fellow Sport's Illustrated model (and Bradley Cooper's baby mama) Irina Shayk commented with a love heart and a kiss face emojis, whilst Lily Aldridge and Chanel Iman left "Congrats" messages.

Justin reposted his wife's pic just a few hours later with a sweet message about her first journey into motherhood.

"You're going to be the most amazing Mum," he wrote.

"I can't wait to start this new journey with you! You're the most thoughtful, loving, caring, and strong woman I've ever met! I'm so proud that our little one is going to be raised in this world by a woman like you! I love you so much."

We're not sure how far along the blonde beauty is, but we're sure this IG pic is the first of many pregnancy updates to come.
