Rosalie Hale
No. In Stephenie Meyer's early drafts of Twilight, Rosalie's first name was originally going to be Carol, but she changed it before it was finalized.
Rosalie Cullen's whole name is Rosalie Hale. Yes, her original name was Rosalie Hale but then the Cullens adopted her and changed her last name to Cullen. Poof! So, now she is Rosalie Cullen.
Rosalie's middle name is Lillian.
Rosalie isn't called Rosalie Cullen, she's Rosalie Hale.
I'm pretty sure it's Rosalie Lillian Hale
When Rosalie was changed, the cullens played up that Rosalie and Jasper looked so alike and so named her Hale. Rosalie Hale. I'm really not sure wat her name was in her human years sorry.
Rosalie Cullen's real name is Rosalie Lillian Hale.
Rosalie Lillian Mcarty hale.
She is not Cullen, but instead Rosalie Hale. Her middle name is never mentioned.
Her name is Rosalie Hale.
Rosalie Lilian Hale
Jasper's last name was originally Whitlock but he changed it when he joined the Cullens with Alice. Jasper uses whatever last name matches the current cover story being used by the Cullens. In Forks, he and Rosalie are pretending to be twins and foster children of the Cullens, so it makes sense that their last name would be the same and not Cullen.
