Oh No, Another Celebrity Marriage bits the Dust, as Chris Rock files for Divorce.

Chris Rock's marriage is kaput -- he's filed to divorce his wife of nearly 20 years. 

Malaak Compton-Rock released a statement Sunday saying, "After much contemplation and 19 years of marriage, Chris and I have decided to go our separate ways."


She adds, "While recognizing that this is a significant change, my children remain at the center of my life and their well-being is my top priority."

Rock's lawyer confirmed he's already filed docs.

The 49-year-old comedian and his wife got married in 1996. They have two daughters -- 12-year-old Lola Simone and 10-year-old Zahra Savannah.

So sad.
