So this is what an heir to a hip-hop fortune looks like.

Jay-Z and Beyonce have released the very first photos of their month-old baby girl, Blue Ivy Carter.

The couple have setup a Tumblr blog showcasing photos of the whole family, and posted a thank you message to all their fans, saying, "We welcome you to share our joy. Thank you for respecting our privacy during this beautiful time in our lives. The Carter family."

Blue Ivy was born on January 7th this year.
