Not that we know of. He didn't seem to be that kind of a guy and he even didn't like the way Fredo welcomed him in Vegas. Later in Cuba we didn't see him with anyone either. He just fell in love with Appolonia, kind of love in the first sight and if you think of that as cheating on his girlfriend. I think he was almost disappointed in going back to the US then.
