Kanye West had to be rescued by security after being mobbed by fans in Swan Lake.

The 'All Day' rapper has been touring Armenia with wife Kim Kardashian West, their 21-month-old daughter North and other members of her family and marked the end of their visit with a free performance in the capital city, Yerevan, yesterday (12.04.15) but things got hectic when ''thousands'' of fans followed his lead and waded into the water.

Before striding into the shallow lake, he told the assembled crowd: ''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!''

As paparazzi scrambled to get a picture, security guards pulled Kanye out from the group of fans and police stopped the gig - which was being live streamed - from continuing.

However, despite the abrupt ending to the set, which lasted just six songs, he and Kim appeared to have enjoyed the mayhem.

His wife tweeted afterwards: ''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)''

The 34-year-old beauty - - whose late father Robert Kardashian was of Armenian-American descent - later took to Twitter again to thank everyone who came out to see her husband perform, and said she was going to miss the country.

Kim tweeted: ''I've learned on this trip how many talented Armenian musicians we have! What an incredible night!!!! Going to miss it here!!! Thank you to everyone who came out last night to see Kanye perform!''

The reality TV star's Armenia trip had been very well-documented on the social media website, as she posted pictures of her, her sister Khloe, and cousins Kourtni and Kara, meeting the Armenian Prime Minister, as well as the two sisters having an ''emotional day'' at the Genocide Museum - which they were visiting for a documentary they're filming about the Armenian Genocide.

Kim tweeted: ''It was an honour to meet the Prime Minister of Armenia, Hovik Abrahamyan. He expressed how proud they are that we are proud Armenians and we have not forgotten our roots. #NeverForget''.
