'It's a distraction,' she said.
'She'll be slightly disappointed with her performance - she needs to make sure she's ready and in the right place.
'I'm really happy with where I am and how it's going, I couldn't ask for more at this stage. I'm happy with what I'm doing - she can do what she wants.'
Despite the confidence boost of her performance, Ennis said she was trying to keep a lid on her expectations of what she could do in London.
'I feel exactly the same as at the start of the year, I believe I can go there and perform and win but I also know [2008 Olympic champion Nataliya] Dobynrksa and others are very capable of doing it as well - there's no clear favourite.
'It's great to win in Gotzis but it's not the Olympics, so there’s still lots of work to do.'
Ennis has made a point of avoiding going to the London Olympic Stadium to keep it new and fresh when the Games come round, but she said she had seen enough pictures to help with her mental preparation and visualisation of her performance.
'If I was going to any other championships, I wouldn't get to visit the track and become familiar with it so I don't want to become too familiar with London,' she said.
'You can visualise your technique and performance without being in the stadium.
'I've seen pictures so I can visualise and I think that's a very important part of the process.'
