Can US citizens who got married in Italy file a divorce in California?

Two US citizens got married in Italy, but never filed marriege in the US. Now we are trying to figure out the fastest way to file a divorce. Would that be filing a divorce in California where we both reside? In such a case, do we still have to divide our assets and property into half?|||California has jurisdiction over your marriage should you choose to file for the divorce there. California is a community property state and more than likely everything will be a shared split.
