LOS ANGELES -- She's been a sensation since she's been born, and now Blue Ivy has made her public debut.

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 include a close-up of the baby and two of each parent holding her.

A statement next to the photos reads, "We welcome you to share our joy." The couple also thanked the public for respecting their privacy.

Blue Ivy is the superstar couple's first child.
