Jay-Z's Roc Nations Sports bolstered its already impressive roster when NBA superstar Kevin Durant signed with the sports management agency today.

Just last week the rapper was officially certified by the National Basketball Players Association and reports cited the Oklahoma City Thunder forward as the first player Jay-Z would sign with his new sports agent license.

"Grateful for this opportunity with Roc Nation Sports," Durant said in a comment that was included on an Instagram photo featuring him and Jay-Z. "It's go time."

On the Instagram post Jay-Z reciprocated the admiration by mentioning he was honored to sign Durant.

"He has a 90.5 [percent] free throw shooting rate, the youngest player in NBA history to join the 50-40-90 club, a giving individual, and a legend in the making," Jay-Z wrote in a comment. "What more can I say?"

Durant is widely regarded as one of the best players in the league, second only to 2013 NBA champion LeBron James. It's not just Durant's skills on the court that have garnered the three-time scoring champion the respect of many, he's also revered for his favorable off-the-court image. Earlier this year Durant donated $1 million to the victims of the tornadoes in Oklahoma.

Durant joins Tulsa Shock guard Sykyar Diggins, New York Yankees second baseman Robinson Cano and New York Jets rookie quarterback Geno Smith on Jay-Z's Roc Nation Sports roster.

The Brooklyn-born entertainer and businessman's foray into sports management hasn't come without controversy, however. Smith's signing is currently under investigation by the National Football League's Player Association to determine whether Jay-Z, who isn't certified with the NFL, violated player union rules by recruiting the rookie quarterback without certification.

Roc Nation is also expected to sign New York Giants wide receiver Victor Curz. Cruz was photographed with Jay-Z's other signees at a party in Manhattan on June 17th to celebrate the 10th anniversary of the rapper's 40/40 sports bar.
