Roc Nation is definitely gunning to be hip-hop's biggest management firm. Young Jeezy is the latest artist to sign with the multi-service powerhouse founded by Jay Z.

The Snowman tweeted a photo of himself and Jay posing to announce the partnership. "CTE x Rocnation x #itsthaworld "Its OFFICIAL," he captioned the flick. Roc Nation resonated the love on social media with the words: "Welcome Jeezy to Roc Nation. CTE x Roc Nation x It's Tha World."

Prior to this, Jeezy was managed by KWL Enterprises, run by former Def Jam and Warner Music Group honcho Kevin Liles. No word on how (if at all) KWL will be a part of Jeezy's career moving forward or the details of the Roc Nation deal.

The rapper is expected to release a solo album soon and recently went on a Twitter tirade against his label, Def Jam Records, for not prioritizing his release. "N----s @ @DefJamRecords keep playing games if you want!" He also threatened to leak his own music.

Roc Nation has management, touring and marketing arms, so it'll be interesting to see exactly how Jeezy's album will roll out under this new deal.

This is the latest in Roc Nation's continued expansion of its roster of talent. Just yesterday, DJ Mustard of 'My Hitta' and 'Rack City' fame inked a deal. Mustard and Jeezy join existing clients like Rihanna and Rita Ora as well as, of course, Hov.
