leannwendy460wmdivamarco.jpgLeAnn Rimes is defending her relationship with Eddie Cibrian yet again ... this time by schooling Wendy Williams for calling her relationship to Cibrian "very sloppy."

On her syndicated talk show, Williams, 46, chats about LeAnn's Shape Magazine interview in which the country crooner discusses her failed marriage to Dean Sheremet. At one point, Williams tells her audience, "It's all very sloppy. The boys have a mother, and her name is Brandi [Glanville]."

Rimes, 28, blasted Williams with the following tweet:

    "All I know is Wendy Williams done pissed my mamma off! I don't wanna be in her path. To say, 'I've reserved myself a place in hell?!' I'm incredibly disappointed to see someone with that kind of platform use it for such negativity and could be so mean and judgmental about a situation they know nothing about...I don't like how it happened either, said it a million times, but this is out of control."

Looks like Mr. Cibrian has a tough country cookie on his hands. You go, girl!
