LeAnn Rimes -- Movin' Out

LeAnn Rimes and her husband Dean Sheremet are finally calling it quits -- on their massive Tennessee mansion.

We now have a good idea why LeAnn and Eddie Cibrian met up at the Lakers game yesterday -- she probably just wanted to platonically tell him that she's selling her place outside of Nashville, Tenn. for $7.45 million.

According to the Real Estalker, the happy couple moved into the place way back in September of 2008 -- no word where LeAnn ... or her husband ... plan to live next.
