Address changed from what was submitted online


The person I am visiting in the U.S. purchased a house of her own and moved to the new house. Hence, the address I submitted online to stay during my trip is now different from where I will actually stay. My interview is in 12 days and I’m worried how to answer the question of where I will be staying during my trip. How can I go about it?
The application was done in September 2018 and the interview is in January 2019.
