The negative of _let's_ is formed in three ways: _let's not_, which is widely used; _don't let's_, which is chiefly found in British English; and _let's don't_, which is an Americanism.
From _Webster's Dictionary of English Usages_
If you are suggesting that you and someone else should not do something, you say *let's not*.
"Let's not talk about it."
"Let's not waste time."
Some British speakers say *don't let's*.
"Don't let's tell anyone."
