Roc Nation just landed its biggest client.

According to a report, Oklahoma City Thunder star Kevin Durant will join Jay-Z and Roc Nation Sports.

Landmark Sports had represented Durant, who was second in the NBA in scoring this season averaging 28.1 points per game.

Landmark also represents Kobe Bryant, Carlos Boozer, Andre Iguodala among others.

Durant will join Yankees 2B Robinson Cano, Jets QB Geno Smith and WNBA star Skylar Diggins as Roc Nation clients.

Eagles WR DeSean Jackson has been rumored to be interested in joining Jay-Z after severing ties with Drew Rosenhaus over a monetary dispute.

Roc Nation is a joint venture between rap mogul Jay-Z and CAA (Creative Artists Agency) which represents dozens of film, music and sports stars.

Last year, a rap video featuring Durant and NBA player Stephen Jackson was released entitled 'Lonely at the Top.'

Liz Mullen, Sports Business Journal first reported the news citing sources.
