Unsubscribing to non-friend?

[Jim J]

I logged into my facebook account, and my friend subscribed to her daughter when I wasn't looking. I think she meant to add her daughter as a friend, but maybe hit subscribe instead. Anyway, she hasn't posted yet so there are no updates on my timeline yet, but I want to unsubscribe to her now.
I went to the facebook help page, but there is no "unsubscribe" button on her homepage. What do I do to get her off my subscription list?
abraXus, is there anyway to physically remove her from my subscriptions list?
Thanks abraXus, I'm surprised facebook doesn't have an option to physically remove her from my list. Weird oversight for a site that huge.
Rogue boy, I'm subscribed to her on Facebook, not Youtube. She wasn't on the Youtube subscription list when I went there.
