Twitter is buzzing about the birth of Beyonce and Jay-Z’s baby Blue, and celebs like Rihanna and Diddy are sending out their well wishes!

Ever since Beyonce gave birth to little Blue Ivy Carter on Jan. 7, everyone’s been talking about the newest celeb baby. Stars like Nick Cannon, Gwyneth Paltrow and more have even sent their congrats and support to Beyonce and Jay-Z — see what they had to say!

Gwyneth sent her love directly to Blue. “Welcome to the world Blue! We love you already,” she wrote. “RT @Sparrow_Teague @GwynethPaltrow is it ivy blue, or blue ivy? so confused..It’s Blue Ivy Carter!”

Blue’s aunt Solange Knowles is so in love with her niece: “The most beautiful girl in the world.” But it looks like Blue has another aunt, too — Jay-Z’s protege Rihanna! “Welcome to the world princess Carter! Love Aunty Rih,” she tweeted.

“Congrats to jay and B! God Bless :)! And many more!” fellow rapper Diddy tweeted to the couple. Meanwhile, Russell Simmons sent his congrats as well: “congrats to my good friends Beyonce and Jay-Z”

Although Snooki isn’t close friends with the couple like Russell, she still tweeted her support. “Beyonce congrats on your baby gurl mama!!!! So happy for you, you deserve it sexpot.”

Brooklyn Decker hoped the baby would share her name. “Oh my gosh Bey had her baby…I hope I hope I hope she is named Brooklyn.. I will tattoo it on my butt if so,” she wrote.

“Congrats beyonce and jay-z on their little child of destiny, Blue Ivy! #watchthecrib,” Ryan Seacrest wrote. Nick Cannon had congrats to share, too. “CANNON’S COUNTDOWN: Congratulations to Jay-Z And Beyonce On Their Baby Girl!”

We’re just as excited about Blue’s arrival as these celebs! Are you, HollywoodLifers?
