Beyoncé and Jay-Z sparked a frenzy when news of their baby girl’s birth made its way online late Saturday night. The couple’s daughter barely made it out of the womb before she was a trending topic on Twitter and lighting up blogs.

Fans and fellow celebrities reacted with joy and congratulatory messages across social networking sites. From Rihanna’s welcome to the newborn to Tyrese’s blessings to Nicki Minaj’s excitement (which could have just been a timing coincidence), their peers couldn’t be happier for the new parents.
