Beyoncé and Jay-Z Introduce Blue Ivy

Meet Blue Ivy Carter! Jay-Z and Beyoncé have introduced their 4-week-old baby girl, sharing multiple photos of her on a new official website.

Born last month, the little one — who has a full head of dark hair — is shown on her own and also being cradled by each of her famous parents, who are clearly beaming with joy.

A handwritten note posted to HelloBlueIvyCarter reads, “We welcome you to share in our joy. Thank you for respecting our privacy during this beautiful time in our lives.” The note is signed “The Carter Family.”

Just this week Beyoncé, 30, made her first post-baby appearance to celebrate husband Jay-Z’s double concert dates at Carnegie Hall.
