My bf wants to name our baby after a chick he knows

Is it acceptable for my bf to ask me to name our baby if it's a girl after a chick he claims is his best friend he talks to her every second calls her beautiful if he needs anything or is upset he runs to her I don't know why he wanted to be with me and have a baby unless she rejected him plus she lives in his home state and we are in a different one to me that just tells me he loves her I'm so hurt he would even ask that of me
