Kanye West and Rihanna preparing joint tour

A Live Nation representative appears to have confirmed rumors suggesting Kanye West and Rihanna are planning a joint tour for 2015 after accidentally listing a collaborative concert in Estonia online.

The FourFiveSeconds hitmakers were recently reported to have agreed to hit the road together later this year (15), but an official announcement has yet to be made.

However, an employee of concert giant Live Nation in Finland let slip that the tour is happening after uploading details for a Kanye & Rihanna show in Tallinn, Estonia on 25 July (15) on the company's website.

The post was quickly removed, but not before eagle-eyed fans could save a screenshot of the news, reports ConsequenceofSound.net.

Representatives for West, Rihanna and Live Nation have yet to comment on the leaked information.

Longtime pals West and Rihanna, who are both working on new albums for release this year (15), previously toured together in 2008, when the Umbrella hitmaker joined the line-up for the hip-hop superstar's Glow In The Dark trek.
