The mom-of-two was performing her song "Do Something" on Friday, Feb. 27, when a mass of blonde hair became detached from her head and attached itself instead to the back of her sexy black catsuit.

As fan video shows, the former Mouseketeer continued her performance with the utmost professionalism, seemingly oblivious to the addition of a blonde tail on the back of her outfit.

As she walked across the stage, the wig-like tresses detached themselves from her costume and fell to the floor.

Spears chopped her trademark long tresses into a short blonde bob back in September, but evidently still enjoys rocking an enhanced, long haired look for her Las Vegas shows.

The 33-year-old singer has recently signed a new residency deal with Planet Hollywood, extending her Vegas Piece of Me show run through 2017.
