This girl already has a hit record, now Blue Ivy Carter has her own Tumblr blog, complete with the first public pictures of Beyonce and Jay-Z's bundle of joy!!

The pictures -- including two of Blue herself, one of each parent holding the newborn and one of little Blue's hand touching her mother's -- were posted to the Tumblr blog, Beyonce and Jay-Z's Facebook pages, and to Jay-Z's website  with a handwritten message signed by "The Carter Family" that reads: "We welcome you to share in our joy. Thank you for respecting our privacy during this Beautiful time in our lives."

Awwwww.
