Translate "Choose your language" text or not?

In our website language selector, we have a text in English saying "Choose your language".

Should that text be ALWAYS in english, or should it also be translated to the current and selected language?

For example, if by mistake I am visiting the Spanish version of the website but I don't speak Spanish, I will not understand "Elige tu idioma". But of course I would understand "Choose your language".
