The Duke and Duchess of Sussex officially welcomed a baby boy on Monday (May 6), and big names from close friends to politicians took to social media with their excitement. Meghan’s royal wedding makeup artist Daniel Martin, former First Lady of the United States (and friend of Meghan!) Michelle Obama, the duchess's Suits co-star Patrick J. Adams and more shared their congratulations.

The Becoming author and former politician, who met with Meghan in secret last year, shared her congratulations.

Dior brand ambassador Daniel took to Instagram to regram the @sussexroyal baby birth announcement, simply captioning it: “Proud #guncle” with a blue heart emoji. He’s been with the duchess through thick and thin, and joined her in New York City for her baby shower in February and even reportedly popped over to London just before her baby was born.

Patrick – who played Meghan's on-screen love interest in Suits – became a first-time father himself just seven months ago, and shared his happiness for the couple. “Just heard that the world just got heavier by 7 pounds and 3 ounces. Much love to him and his incredible parents. Learned first hand 7 months ago how transformational becoming a parent is and couldn’t be happier for Meghan and Harry as they begin this adventure. #playdatesoon,” he wrote on Twitter.

Another one of Meghan's close Suits co-stars, Sarah Rafferty, took to Twitter to share her happiness, too. “Hearts are leaping for a beautiful, wondrous and healthy baby boy,” she tweeted.

One of Meghan's closest friends, Priyanka Chopra, took to her Instagram story to show her support, too!

Wendy, 54, tweeted her excitement, too, writing: “IT'S A BOY!”

British Prime Minister Theresa May also posted a sweet message for the couple. “Congratulations to the Duke and Duchess of Sussex on the arrival of their baby boy. Wishing you all the best at this happy time,” she wrote on Twitter.
