Prepare for the best thing you'll watch all day.
In a well-executed prank, Britney Spears' two sons, Sean Preston and Jayden James worked together to scare the lights out of their famous mom. As seen in a video taped on the songstress' phone, the kids wait for an unsuspecting Spears to walk by them before unexpectedly screaming at her.
"We're about to scare the heck out of mom," Sean explains in front of the camera as Jayden videotapes him. "We just stole her phone."
The pop star was physically knocked to her feet by the scare, screaming "Preston!" as she fell to the floor and gripped her dress.
