Yolanda cites the usual -- irreconcilable differences. She wants spousal support. There are no child support or custody issues ... they had no kids together.
As we reported, Yolanda and David had a prenup. He's already set her up in a $5 million swanky West L.A. condo.
The couple married in November, 2011. She says they separated 2 months ago.
It was Yolanda's second marriage and David's fourth.
