Beyonce Knowles holds her daughter Blue Ivy (AP Photo/Ed Burke for Beyonce.com)
Five photos of the 1-month-old were posted by her parents - Beyonce and Jay-Z - on a page at the blogging service Tumblr.
The pictures at http://helloblueivycarter.tumblr.com include a close-up of the baby and two of each parent holding her. Blue Ivy is their first child.
A statement next to the photos reads, "We welcome you to share our joy."
The couple also thanked the public for respecting their privacy.
Beyonce and Jay-Z are the latest celebrities to shun big bucks from the tabloid press for exclusive rights to baby pictures and instead post the photos on a public website for free.
Mariah Carey and Nick Cannon debuted their twins in the same way last year.
