Guns N' Roses are set to be supported by Otherkin during Not In This Lifetime Tour.

The rock band are reportedly set to be accompanied by the 'Ay Ay' vocalists, as well as Mark Langean and Royal Blood when they take to the stage at their sold-out gig at Slane Castle in the Republic of Ireland on May 27, which will mark the group's first return after 25 years.

And Lord Henry Mountcharles, who is known for setting up a variety of concerts at his home, is ''delighted'' with the line-up next month, the Belfast Telegraph has reported.

Speaking about the upcoming musical event, he said: ''I am delighted with this line up. Royal Blood is a really exciting act and I am thrilled they are on the bill. The local connection with Otherkin is special.''

And Otherkin, who are fronted by Luke Reilly, have taken to social media to broadcast their excitement ahead of the event.

They tweeted: ''INSANELY EXCITED TO ANNOUNCE THAT WE'LL BE SUPPORTING Guns 'n' Roses AT SLANE CASTLE. 2017, YEAR OF THE 'KIN xx (sic).''

The 'Sweet Child O' Mine' hitmaker's is in high demand as 80,000 tickets for the concert, which went on sale in December last year, have all been snatched up by loyal fans.
