"MADtv" funnyman Aries Spears isn't laughing at this punch line ... TMZ has learned, his wife of 2 years has filed for divorce.
Spears' wife Elisa Larregui filed the docs in L.A. County Superior Court, citing "irreconcilable differences." The two were married back in December 2010 and separated on February 5th. They have one 3-year-old son.
According to the divorce docs, Elisa wants full legal and physical custody of their son. Elisa only wants Aries to be allowed MONITORED visitation. She also wants spousal support.
So far, it's unclear how Aries and Elisa plan to divide their assets.
We reached out to Aries Spears for comment -- so far, no word back.
