National Britney Spears Comeback Day is finally here, and we have a 27th birthday, an album release, actual tour dates and two Good Morning America performances to commemorate this very special event.

Brit-Brit put on her best non-Madonna ringleader costume and performed her new single “Circus” as well as “Womanizer” (after the jump, but it’s no different than her three European performances this weekend—same walking around and a dude getting beat up). All this fun took place under a giant circusy tent complete with jugglers, clowns and the Spears fam, including Mama Lynne, Papa Jamie and her boys Sean Preston and Jayden James.

After Brit finished up with "Womanizer," Diane Sawyer and Robin Roberts wished the pop princess a happy birthday—as did Hugh Jackman, Reese Witherspoon and Taylor Swift via videotaped messages. Britney seemed just as confused by this part of the show as we were.

Check out her performances and then let us know how you plan to celebrate National Britney Comeback Day.
