Yung Joc's Wife -- Keep Your Sidepiece -- I'm Divorcing You!


The wife of "Love and Hip Hop" star Yung Joc must have finally reached her tolerance level of watching her hubby and his sidepiece on TV ... so she's pulling the plug on their marriage.

Alexandria Robinson filed to divorce the 31-year-old rapper. They were high school sweethearts and have been married for 13 years.  They have 3 kids.

Alexandria acknowledges in her docs ... she and Joc have been separated since Feb. 2012.  

She wants the works -- spousal and child support.  She says she only pulls in $1,875 a month.  But she's banking on getting royalties from his music publishing rights.

Not surprisingly, Alexandria cites adultery as grounds for the divorce.

Joc's been carrying on a high profile relationship with Karlie Redd on "Love & Hip Hop: Atlanta." They live together on the show.  And get this ... the GF gets really pissed off when she suspected he cheated on her.
