Gwyneth, Rihanna, Diddy, Seacrest Tweet (and Tattoo?!) Baby Congrats to Beyoncé and Jay-Z!

Best wishes pour out from fellow A-listers in wake of the birth of music royalty's first daughter over the weekend

Watch the crib.

That's what Beyoncé and Jay-Z fans the world over spent the weekend doing, as it wasn't long after daughter Blue Ivy Carter was born Saturday night that she not only had her own (fake, obviously) Twitter account but was already a worldwide trending topic.

And that's thanks in no small part to the countless superstar celebrity pals who wasted no time in sending out congratulations to the first-time parents. Naturally, first among them was B.'s A-list BFF Gwyneth Paltrow (who knows from eyebrow-raising baby monikers), who also gets the kudos for clarifying the initial name confusion over Baby Blue. Way to go, Auntie G.

In any case, Blue Ivy has racked up enough goodwill over the last two days to last a lifetime. Here's a taste:

• Gwyneth Paltrow: "Welcome to the world Blue! We love you already…It's Blue Ivy Carter!"

• Rihanna: "Welcome to the world princess Carter! Love Aunty Rih."

• Solange Knowles: "The most beautiful girl in the world."

What are the FACTS people?! I'm not above needing to know this information…Ivy Blue Carter. They named her Ivy Blue Carter.. we can no longer be bonded. I'll go cry myself to sleep now."
