Move over, Paranormal Activity franchise: It's Scaredney, b---h!

Late Wednesday night, Britney Spears shared an adorable home video/terrifying found footage horror movie of her two sons, Sean Preston, 11, and Jayden James, 10, pranking her before bedtime.

"We’re about to scare the heck out of mom," Sean Preston announces confidently in the grainy clip, as his younger brother films using the Piece of Me star's cell phone. (Could the prank be light payback for all the times the boys' famous parent teased them with her Woody Woodpecker impression-giving, Michael Jackson-singing Instagram antics?)

"We just stole her phone and she's gonna come… she’s walking!" Sean Preston then whispers as he catches sight of their victim.

The September birthday boys, who enjoyed a Pokemon-themed joint party on September 12, quickly hide behind a wall, and as Britney rounds the corner seemingly into her bedroom, her eldest son emerges with a loud, scary yell, visibly jolting his mother.

Startled, shaken and shook, the "Make Me" singer recoils and crumples to the floor with a deafening shriek.

"Sean Preston!" the pop star-turned-scream-queen shouts, before her son erupts into a fit of evil giggles, sounding a little bit like Nelson from The Simpsons.

Watch the horrifying ordeal below... if you dare.
