Kim Jong-un was reportedly hauled from his expensive private school after spies exposed his love of BDSM porn.
The North Korean leader, now 36, attended a boarding school in Bern, Switzerland, in the 1990s.
But he was ordered home by his father Kim Jong-il after spies informed him his son had been caught with a kinky magazine stuffed in his school bag.
Kim Jong-un attended the school with his three siblings - who all lived there under fake identities as the children of a North Korean diplomat.
After the now 36-year-old Jong-un was caught with the porn magazine, all four children were ordered to return home, reports the Daily Star.

Sources said the children's father was growing increasingly worried that his children were being led astray by their western peers.
It's is believed the magazines were found when teachers searched his bag for 'cheat sheets' ahead of exams.
The despotic leader still holds a deep love for all things Swiss, and gifts his statesmen with expensive Swiss watches.
Details of the embarrassing incident come after much speculation about Kim Jong-un's rumoured death.

As rumours swirl that the 'Supreme Leader' of the secretive, totalitarian state has in fact died, a video from July 28, 2017 has sleuths claiming near-perfect body-doubles could have stood in for him on several occasions and without the watching world being any the wiser.
In the footage, Kim chats to the lookalikes as he oversees the launch of the Hwasong-14 missile.
They sport Kim's distinctive haircut and are dressed in the same clothing. Kim is rarely seen without a pair of Cuban heels on his feet and a black pinstripe suit.
The despot is known to travel with body doubles to thwart assassination attempts.
But when the terrible tyrant went missing for three weeks in April and suddenly reappeared - supposedly on a visit to a fertiliser factory - as observers across the world were convinced of his death, speculation turned to whether the figure we were seeing was in fact one of his lookalikes.
Online, people pored over the latest pictures of the dictator, analysing his wrinkles, teeth, nose, ears and hairline.
One photo seems to show the leader's teeth looking straighter and whiter than before.
There have been suggestions that the photo was doctored, or that Kim's teeth had been altered via a relatively simple proceedure.
Others claim Kim's earlobes seem to no longer attach to his head with a smooth curve in recent pictures.
