Uh-oh. Maybe it’s time for Britney to re-enroll in those parenting classes?

Britney Spears’ toddler sons, Sean Preston, 3, and Jayden James, 2, are accused of causing all sorts of damage to a $2,000-a-night suite at the Mohegan Sun Resort & Casino — where the family stayed during Brit’s Circus Tour stop in Ucansville, Connecticut earlier this month.

“The boys pulled down the silk drapes and broke an expensive vase in the living room,” a hotel employee blabbed to celebrity gossip columnist Shelby Loosch this week. “They also left crayon marks all over the walls.”

And it gets worse, as Loosch writes, “…One of the boys messed in his pants while in the pool — leaving other swimmers horrified.”
