Rapper Nas has had to scrap his upcoming London concert with Damian Marley as a result of the flight chaos caused by the volcanic eruption in Iceland.
Air travel across the whole of Europe has been disrupted for days due to the heavy cloud of volcanic ash floating above the continent, which can cause jet engines to fail.
Over 63,000 flights have been cancelled, costing airlines $200 million (£125 million) a day and affecting six million passengers worldwide - and Nas and Marley are among those who have been forced to alter their travel plans, according to AllHipHop.com.
The pair was due to perform at London's Electric Ballroom on Wednesday (21Apr10) in support of their new collaborative album, Distant Relatives - but that show has now been shelved because they are unable to fly over from the U.S.
The hip-hop stars aren't the only artists whose international tours have been affected by the eruption - R&B superstar Usher has also had to put plans to tour the U.K. on hold until the European air space opens up.
The Yeah! hitmaker was expected to fly to Europe to promote his new song OMG, which hit the top of the U.K. singles chart on Sunday (18Apr10).
