Most beautiful or beautifulest

Most beautiful or beautifulest
 

And don't British people say most beautiful as beautifulest?

Moved from this thread, since this is really a new topic.

I think that it are both sentences or phrases mean the same, because the United States has a form to speak different to England, for example Mexico and Spain, all we speak Spanish but our idioms or form to speak is distinct.

But the words mean the same.

Both mean the same but most beautiful is gramatically correct.
If you use beautifulest:bad: you may be judged for not mastering English.
:thumbsup:In both Great Britain and United States most beautiful is the best way to say it.

Jchen,
British English also say, beautiful..., more beautiful..., most beautiful.

ok ok I got it now I understand it now.
Thanks everyone
