The 'Formation' singer uploaded a handful of pics from the posh bash to her Tumblr page.
Uh, happy belated birthday, Blue Ivy?
Beyoncé has been so busy over the past few months performing at the Super Bowl, rehearsing for a world tour, releasing a clothing line and not releasing a new album -- yet! Where that album at, B? -- that she's only now getting around to uploading pictures from her daughter's 4th birthday party.
Better late than never, because the photos are adorable. (Obviously, it's Blue Ivy, after all.)

Blue's, ahem, "b'day" was actually Jan. 7, and it appears the Carters celebrated with a fairy-themed party, complete with tutus and a special visit from some fairy princesses.
The outdoor party space was decked out in flowers, with teepees to lounge in and racks of fairy dresses to change into.

Taking a page from her mama's book, Blue had at least one outfit change during the shindig, switching into a purple butterfly dress and tiara to try her hand at archery.
Just another reminder that it's good to be Blue.
Meanwhile, Queen Bey recently opened up about how she was "underestimated" in Destiny's Child and the real message behind "Formation." Find out what she had to say in the video below.
