A couple of little pranksters gave Britney Spears the fright of her entire life and there's some hilarious video evidence.

Happy Friday, people.

These pranksters were actually Brit's sons' Sean, 11 and Jayden, 10, who decided to cheekily film the incident on their mum's phone.

The video begins when Jayden films brother Sean, revealing to the camera:"We’re about to scare the heck out of mom. We just stole her phone and she's going to go nuts.”

Then the 34-year-old comes walking round the corner and hers sons scream to scare her, to which she then tumbles into a heap onto the floor and shouts "Preston!" and one of the boys shouts "HA HA!"

Cheeky boys!

Luckily, Brit saw the hilarious side and even postedthe clip on her Instagram, captioning it: "My damn kids :)"

Brit has previously told Flauntmagazine that having children has changed her life and now she's done a"complete 360" on howshe used to be.

She revealed: "Everything is on a way lower scale. I'm actually a very boring person. I don't go out. I don't really do anything."
