US citizenship in problem?

Question

My family settled in US many years ago but I was holding greencard when i came to Italy (my birh place) and married an intalian girl. After marriage she stayed there while i came back to USA. And at my US citizenship I did NOT show my marriage to immigration records.

Now can i marry in US as no one knows about my italian marriage?

Secondly, if my marriage in italy comes to knowledge of USCIS what may happen?

Thirdly can i sponsor my girlfriend in US on my existing papers which show i am single.
