MTN welcomed Cassper Nyovest as their new brand ambassador yesterday. The rapper took to Twitter to announce what he calls "the biggest endorsement deal in South African Music history."

According to Hype Magazine, the deal will in part involve Cassper becoming the face of the brand across the continent. The monetary details of the deal were not specified but some have tweeted their support for the "R10 million" deal.

The deal was signed in the presence of DJ, music producer and businessman Oskido, whose Kalawa record company helped to manage the distribution of Cassper’s first album.

“The partnership with MTN is a natural progression in my career. I’ve always sought to associate myself and the Cassper Nyovest brand with organisations and initiatives that unashamedly champion the development of music. I have found a home at MTN and I wish to make this partnership worthwhile for MTN customers,” Nyovest said in a statement.

Nyovest's career is in an upward spiral with the biggest one man show in the country, Fill Up The Dome, scheduled  to take place on October 31st and his sophomore album, 'Refiloe' coming out next week.

Cassper also has the support of TV personality and actress girlfriend Boitumelo Thulo.
