Parliamentarian Namal Rajapaksa, a National rugby player himself, who is involved with Carlton, tweeted saying that the two big names will be in Sri Lanka for the concert on the 12th of July.
Grammy award-winning US hip hop artist, Nelly, is currently in the charts with Hey Porsche, the first single from his upcoming seventh album, titled M.O.
The album is scheduled for release in June 2013, and currently has a long list of featured artists rumoured to be involved in the project.
Kingston is meanwhile popular in Sri Lanka at the moment with his track Back 2 Life taken off the album with the same name.
For his third-full length album Back 2 Life, Sean Kingston immensely expanded his songwriting role, nixed the multi-producer approach of his last release, and pushed for a fresh new sound.
But on Back 2 Life, the singer/songwriter blends his newly strengthened vocals with fiercely inventive electronic effects and hard-hitting live instrumentation to offer up his most passionately inspired work.
