Looks like has a little prankster on her hands.
On Monday, her 11-year-old son Jayden James Federline posted a video of him stealing his mom's phone and attempting to spook her.
"I stole it and I'm going to scare her with it," the young man said before belting out a scream.
The joke startled Spears, too.
"Jayden! Not funny," she said, spurring a laugh from her son.
This isn't the first time the singer's kids have given her a scare. In 2016, Sean Preston Federline, 12, assisted his brother in a similar prank, where they (again!) stole their mom's phone and screamed. The "Toxic" singer fell to the floor in fear.
Spears shared a video of the shenanigans on Instagram and captured it "my damn kids."
Then again, Spears has pulled a few pranks of her own. In 2016, the "Piece of Me" star woke a slumbering with a full-fledged performance. She also pulled a practical joke on three bodyguards for the show Best Time Ever With Neil Patrick Harris in 2015.
When they aren't scaring each other, the trio likes to enjoy a little family time. Spears recently shared a video of her playing basketball with her boys.
Spears shares her two children with her ex, whom she was married to for two years.
Spears filed for divorce in 2006.
