The star, who will be saying 'I do', after fiancé Russell popped the question during a romantic trip to India, has already let slip some wedding details.
And now the I Kissed a Girl singer has let US magazine People in on some more secrets.
Although the star has always said she would like to marry in her home town of Santa Barbara, she's now hinting that the ceremony may be taking place somewhere different entirely.
'We don't necessarily want it to be a drunk fest of people just, you know, one night and then forgetting about it,' she said.
'We want it to be about the love. So sometimes to be about the love, we have to take them out of their comfort zone.'
Lovely Katy also let slip some thoughts on her wedding ensemble, revealing she's been talking to friend John Galliano about designing the dress for her big day.
'We have been kind of talking to John Galliano because that was the first fashion show in Paris that we kind of came out as a couple,' she told People.
'So if we did Galliano, it would make it full circle.'
We can't help thinking this is going to be one spectacular wedding!
