Legend of a fall.

Britney Spears fell on stage during her Piece of Me show on Wednesday.

Britney closes out the show with a casual freestyle during “Till The World Ends.” It appears her knee buckled while bopping up and down, forcing her to stumble and fall to the ground. She finished the show with a bow before her dancers helped her hobble off stage.

No word on how seriously injured Britney is, if at all, or if it will affect her upcoming Billboard music awards performance with Iggy Azalea next month.

Britney famously hurt her knee during a music video shoot for the song “Outrageous” back in 2004.

UPDATE: She’s okay, y’all!

Send Britney well wishes!
