Is Vitani Scar's daughter?

[PrincessKiara]

I know there is no evidence that either Nuka or Vitani are Scar`s cubs, but I do like the idea that Nuka is his. This is of course just my opinion/a theory.
As for Vitani, I don`t think Scar is her father, mainly because she and Kovu appear to be littermates (and we all know Kovu is not his son) and Vitanis looks vary greatly from both Scar and Zira. I do not think Vitani is Scars daughter.
