On a brand-new tumblr site dedicated to their baby girl "helloblueivycarter," a handwritten note reads, "We welcome you to share in our joy. Thank you for respecting our privacy during this beautiful time in our lives. The Carter Family."
Born in NYC Jan. 7 and weighing in at 7 lbs., Blue Carter gets her debut in five adorable photos; in one open-eyed closeup, the music super couple's first child looks every bit the spitting image of her mom, 30.
In another pic, Beyonce beams as she holds her little one close; in another shot, proud papa Jay-Z, 42 (real name: Shawn Carter) also smiles from ear to ear with Blue resting on his chest. (The rapper famously penned and recorded the song "Glory" soon after his daughter's birth.) An additional photo reveals Blue's tiny hand reaching out to her mom's.
