Photos syncing with another phone

[AC Question]

Hi,

I have a s4 and my photos are backing up on my phone via google plus but they are also backing up on my partners s4. I have checked our settings on google plus and there is no obvious reason why this is happening. It is very frustrating as we are getting married soon and all the photos I have of my wedding dress is backing up on his phone. Can anybody tell me how I stop this?
