Alright, I think that covers the main points. Now organize the information into the specified format.

Double-check the spelling of her name and film titles. Sometimes she's referred to as Nayanthara or Nayantharaa. I think it's Nayanthara. Confirm her correct name. Also, verify her husband's name is Vignesh Shivan.

Next, lifestyle. So I should include her personal life details, maybe her family, education, interests. Maybe her journey from a child artist to a leading actress. Also, her achievements and awards would be relevant here.

Entertainment part would involve her recent projects, upcoming movies, social media presence, her role in the industry, and maybe some interesting facts or trivia. Also, how she's portrayed in the media and her influence in South Indian cinema.

I need to structure this guide in sections. Start with an introduction about her, then a section on her lifestyle and personal life, then entertainment contributions, and finally address the video download links with a disclaimer about legal methods.

Make sure to mention her notable roles, like in "Veeram," "Thuppaki," "Maari," "Kaththi," etc. For the legal download options, OTT platforms like YouTube, SonyLIV, Netflix, Amazon Prime could be where her movies are available. Suggest users check these platforms.
