Keeping your personal life private is a task when you are a public figure working in the film industry in India. However, Keerthy Suresh did the seemingly impossible as she dated Antony Thattil for 15 years without the media or fans getting to know about it. Even as she got linked with artists from the industry, the National Award winning actress kept mum. She only disclosed her relationship days before her marriage to Antony Thattil. The couple had a beautiful Tamil-styled and later a church wedding ceremony in Goa in December 2024. 

Keerthy revealed that very few people in the industry were aware of her relationship with Antony. “Nobody knew; only close friends of mine knew. And even in the industry, Sam (Samantha Ruth Prabhu) knew, Jagadish (Palanisamy) had been a part of the journey from the beginning, Atlee, Priya, Vijay sir, Kalyani (Priyadarshan), Aishwarya Lekshmi…very few people, our friends, from the industry knew, " she told Galatta India in an interview. She said that she chose to keep her relationship out of the public eye.
