Photobucket connected to my Mom's Facebook?

I've had my Photobucket for three years, and keep my pictures and album private.

One day, when I logged on, however, I noticed that my mother's Facebook avatar was now my Photobucket avatar. I don't have a Facebook, and she's never used my Photobucket to share any pictures, so I don't know how this could have happened. But now, they're somehow connected, and I'm slightly worried.

Could someone please explain how this happened, and how I can stop the connection? Thanks.
