Teenage Renesmee in Twilight: Breaking Dawn Part 1?

Aite. So I just watched Twilight Breaking Dawn Part 1 (yeah, I'm so late)

and during the scene where Jacob imprinted on Renesmee he sorta' had a "flash forward" scene talking about imprinting and stuff.

And there are scenes of Renesmee in it, also showing them holding hands..

I'm 99% sure that those scenes are going to be included in Twilight Breaking Dawn Part 2 since I see Mackenzie Foy in those scenes (young Renesmee).

But there were also scenes of teen Renesmee (when she stopped ageing), and I'm 100% sure that she is going to be portraying the main Renesmee when she stops ageing.

But I have no idea who she is, what the actresses name is, etc.

Most of you who clicked on this question probably have watched it already, but if you can't remember how she looks like here a link to her picture, taken from the Twilight wikia website.

I just want you Twilight fans to confirm whether she is the REAL actress who's going to be portraying the main Renesmee, and if you could give me some sources/articles/links of any sites confirming that the girl in the picture is Renesmee, please do so :D

And include her real name too.

Thanks,
