Don't ever accuse Britney Spears of not dancing hard enough.
The 33-year-old singer was putting on a particularly fierce performance of her hit "Do Somethin'" during her Piece of Me show in Las Vegas last week, when a noticeable chunk of her blonde hair extensions came out mid-chorus.
Though like the true professional she is, Britney barely batted an eye, and didn't even seem to notice the little hiccup.
This isn't the first style malfunction the "Oops!... I Did It Again" has suffered during her Piece of Me tour -- in December 2013, her glittery jumpsuit popped open in the back during her performance of "Circus," threatening to expose a little bit too much of the pop princess.
But as the seasoned pro will probably tell you, the show must go on!
One singer who’ll undoubtedly feel her pain is Madonna, who recently suffered a horrible fall during her "Living For Love" performance at the Brit Awards.
