It was later reported Hyon Song-wol had been executed alongside eleven other members of her pop group, after being accused of filming themselves have sex with each other and selling the videos.
Other musicians linked to the 12 who allegedly died were forced to watch the grisly killings. They were then sent to labour camps, victims of the regime's policy of collective punishment.
However, in yet another twist, Hyon Song-Wol appeared alive and well on North Korean television in 2014.
5. His wife goes for months without being seen
After demonstrating his ruthlessness with numerous executions, Kim Jong-Un fuelled rumours he had turned against his own wife.
The fate of Ri Sol-Ju, a former singer whom Kim married in 2009, is often the subject of speculation as she goes for weeks without being seen in public.
Speculation soared in December 2013 when media pointed out Ri had not been seen in public since October.

However, the Daily Mail reported she appeared on state TV on December 18, 2013 at a memorial service for Kim Jong-Un's father.
Rumours Ri was missing began to circulate again when she wasn't seen in public for four months - reappearing with her husband in April 2015 after not being seen since December the previous year.
