Christina Applegate's Ex-Husband -- Divorcing Again - Jana Rae Kramer Divorce

Christina Applegate's ex-husband Johnathon Schaech is about to be the ex-husband of another actress -- because Schaech's current wife just filed for divorce ... less than two months after they wed. 

According to legal documents filed in L.A. County Superior Court -- and obtained by TMZ -- "One Tree Hill" actress Jana Rae Kramer filed for dissolution of marriage on August 20.

The couple tied the knot on July 4th -- and announced their split less than a month later.

Schaech went through the whole divorce thing with Christina Applegate back in 2007.

UPDATE: In the divorce docs, it shows the couple was only married for 12 days before separating.
