After 16 years of marriage, it's over for 'Dog Whisperer' star Cesar Millan and his wife, Illusion, according to the star's website.

TMZ reports that Illusion Millan filed for divorce in Los Angeles court today citing irreconcilable differences. She is seeking custody of their two sons, Andrew and Calvin, and spousal support.

"We are sad to announce that after 16 years of marriage we have decided to file for divorce," reads the statement on Cesar's website. "The decision was made after much consideration and time. We remain caring friends, and are fully committed to the co-parenting of our two boys." The statement was posted earlier today.
