Should I be mad?

So my husband got a message from an old friend who actually was in love with him when they were younger but he never liked her back but they remained friends. Anyways she wrote a book that's supposed to be published and I guess my husband is in the book. So she was asking him permission to use his name. I don't know why but it bothered me. My husband doesn't care because she said he'd get paid for it but I feel like it's inappropriate. And I don't think he'll get much either anyways. I just want to know if I'm overreacting or if I'm right to feel the way I do about it.
