TMZ reports Elvira filed the legal docs on Friday, citing irreconcilable differences. She is asking for spousal support.
Schneider said in a statement, "It's true that after 21 years, Elly and I are getting divorced. The glue that held us together has weakened, and I feel it's the only way to not only salvage our friendship, but to remain a good example to our children. When you have children together, you are together until death do you part. That much is obvious. I am, of course, saddened by this personal failing, but feel it's important to get this part correct, even if I couldn't get the other part correct. This is all I have to say on the matter. Please respect my privacy, as well as Elly's, and refrain from asking either one of us for further comments."
The two married in 1993 and have two adult children.
Schneider was previously married to former L.A. news anchor Tawny Little.
