Kanye West performed a free concert in Yerevan, Armenia on Sunday (12.04.15).

The hip-hop star, who's been visiting the country alongside his wife Kim Kardashian West and their 21-month-old daughter North, decided to stage a concert in the country's capital.

However, such is his popularity, Kanye had to be rescued by security after being mobbed by fans in Swan Lake because ''thousands'' of fans followed him into the water.

Before going into the water, he said: ''Over there, can y'all see me over there? We're going to do something different right now, like, like, like we always do it this time!''

The gig - which was being live streamed - had to be stopped because of the ensuing chaos, but that didn't seem to dampen the enthusiasm of Kanye or his wife.

Kim, 34, tweeted: ''Crazy night! Kanye wakes me up & says he's doing a free concert in Yerevan, Armenia! I throw on sweats & we go! Thousands of people were there! Kanye jumped in swan lake to be closer to the crowd on the other side & so many people jumped in too! Such an exciting crazy night! So happy I got to rock out with everyone in Armenia on our last night here!!!! #EpicNight #ArmenianPride (sic)''
