Los Angeles Mayor Antonio Villaraigosa’s wife of twenty years, Corina Villaraigosa, filed for divorce today on grounds of irreconcilable differences. The two share a 14 year old daughter and a 19 year old son. The news comes within months of Villaraigosa’s confession that his marriage was subject to “ups and downs”. Villaraigosa was recently caught in an affair with Spanish anchor Mirthala Salinas.
