Tessa Ortega’s age isn’t completely consistent across public sources, and there appear to be multiple public figures with that name (including at least one TikTok/content creator and at least one actress/singer).

Because of that, there is no single, fully reliable “official” answer to how old is Tessa Ortega without specifying which Tessa Ortega you mean (for example, the TikTok star versus an actress with the same name).

If you can clarify which Tessa Ortega (TikTok creator, actress, or another context), I can narrow down what publicly available information says about that specific person’s age, or explain why it remains uncertain.
