Absolutely no. Zira is Vitani's biological mother. Any videos that toon things like that of anything that has to do with a non-Disney character that isn't from the film is 100% fanmade. That's just made up door someone who believes in a different story line that filmmakers did not add to the film. Many fans believe some characters (especially those from outsider boeken 'TLK: SNA') that are NOT Disney creation, exist in the film rather than following the true canon.
