Could you provide some clarity on the question "How old is Alex Warren TikTok?"? It seems a bit ambiguous as it refers to both a person's name and a popular social media platform. If you're inquiring about the age of an individual named Alex Warren who is active on TikTok, then the answer would depend on the specific individual's birthdate. However, if you're referring to the platform itself, TikTok is not a person and thus doesn't have an age. If you're referring to a specific account or user, please clarify the context so I can provide a more accurate response.
