From japanese to english is very difficult. Japanese phonology (especially their parameters such as the consonant-vowel-consonant-vowel structure) is very limited, while english has a very rich phonology.
Grammar-wise it's a very large step also. Since Japanese is an isolate language, it's got no connection to English, which is an Indo-European language. So engRish is very logical and for Ayu probably not intentional.
But I'm sure that with so many years as a celebrity, she had to work in English loads of times. So yea. I'm sure she can understand a whole lot.
besides.. Ayu studied English in Las Vegas a few years ago
