Is it wrong of me to ask my husband to take a DNA test?

This girl swears up and down my husband is the father. We will nickname this girl”Nikki” He told his mom it wasn’t his and his mom side of the family said it wasn’t his either. His sister said the baby don’t look nothing like him at all. He told his dad it was his child. His father said he hasn’t heard from the girl in a while but she stayed on his phone every night talking about my husband isn’t doing anything for the child. I asked my husband about this and he said something is mentally wrong with her. His father fought for the child to have some of my husband money, and now she has disappeared again. My husband father kept pressuring my husband to take care of the child. I tried to call Nikki and her number is disconnected. I told him that I want a court ordered DNA test and he is willing to take one. his daddy said that he hasn’t heard from her in a while and she stopped calling him. Nikki went from calling his daddy every night to not calling him at all. Years ago I called her and she told me the baby was his. Now I called the exact same number and it’s disconnected. Nikki has now disappeared again. I been trying to make contact with Nikki over the years and she keeps disappearing. She won’t talk to me or his mom. She stayed calling his daddy
