Pop star tells fan 'you're a f**king a**hole'

During Britney Spears' April 15 concert in Vegas, the ‘Piece of Me’ singer had one jaw-dropping outburst... She called a fan out for being a 'f–king a–hole!'

The 33-year-old pop star had just finished a song and asked the crowd if they were ready for another show-stopping performance.

According to TMZ, someone in the audience called her a ''fat b**ch'' and in response, while her mic was still on, Britney says... 'f**king a**hole.''

Meanwhile critics of her show say she walks through her performance like a robot eventhough on that April 15 night, her antennas are up!

It's obvious the mother-of-two doesn't take crap from random people and wouldn't hesitate to put them in check.
