I'm based in the US, where it's spelled without the "u". Quite a few examples of this spelling difference - humo(u)r, behavio(u)r etc. Oh and "spelt" is "spelled". Isn't English fun! :)
Maybe this is my own idiosyncrasy though and not what others would do. I’ve never even thought about it until just now.
Based on context, I assume you mean a native "American English" speaker, rather than a "Native American" English speaker :)

The Americans and the British, one people separated by a common language.
