Torbie or a Tortie?

Hi there. I just adopted this little girl. Her coat is strikingly unusual. The shelter said she was a Torbie. Would you cat fanciers agree?

Here's another photo of Gemma.

No she is a beautiful Tortie. A torbie is a tortie and tabby mix. I don't see any tabby lines on her unless they don't show in the picture. 

I don't see any tabby lines on her either. She is a pretty girl. I just wonder if she'll be headstrong.

You know I had a Tortie last year Callie. She was so awesome. She was the resident mom of my cats. When ever a new foster would come in and was scared she would take over like I am here baby. She would groom them, play and just be Momma. She was the Alpha though she seemed not to be dominate.
