Who is driving Britney Spears “crazy” nowadays? Her two sons, of course.

Jayden James, 10, and Sean Preston, 11, made a guest appearance on their mother’s Instagram this morning for a practical joke they pulled on the pop star that sent her falling to the ground in fear.

In the clip, Preston reveals that they’ve stolen Spears’ phone and they’re about to “scare the heck out of mom.” It’s likely that younger brother Jayden is playing cameraman.

When the pranksters hear Spears, 34, making her way over, they fall silent until Preston jumps out and yells at his unsuspecting mom.

Spears flinches as she screams and falls to the floor before letting out an angry, “Sean Preston!” (You know she means business when she uses both first and middle names.)

The Las Vegas performer captioned the video, “My damn kids,” complete with a laughing with tears emoji.

Earlier this month, the boys jointly celebrated their birthdays — they’re one year and two days apart — with a Pokémon-themed pool party complete with a Pikachu-topped cake, balloons, Poké Balls with the boys’ names inscribed on them and cake pops shaped like various critters from the game.
