Boys will be boys.

My damn kids ?

Boys will be boys.

Britney’s sons Preston and Jayden (who celebrated their 11th and 10th birthdays earlier this month) stole their mom’s iPhone and planned a sneak attack to scare the pop princess.

Preston screams at an unsuspecting Britney, who flails to the floor in horror.

She must have had a good laugh about it afterward, because she posted it on Instagram for us all to cackle over.

She affectionately captioned it: “My damn kids ?”

Watch above.
