LeAnn Rimes and Dean Sheremet's divorce was finalized Saturday. The former couple reached a settlement in December 2009, a few days after they filed for divorce.
Sheremet, 29, and Rimes -- who wed in 2002 -- separated that summer. Cibrian and his wife, Brandi Glanville, the mother of his two sons, are also in the process of divorcing.
Rimes recently said she was "selfish" for having an affair and that she hates that "people got hurt."

He was dropped from CSI: Miami on Thursday.
