"comment ça va ma belle" ou "Salut ma belle"
I was listening to a radio station from Belgium. Listeners could call to the presenters during the radio program. For a lot of female listeners one male presenter always said "Ça va ma belle" or "Salut ma belle". Only one presenter said greetings like this.

My question: is this greeting common?
