An interesting aspect about the video is that Shivani had also sung her wishes to leading Tamil film actor Sivakarthikeyan, who as well shares his birthday today (February 17) with Rio. Shivani's fans know quite well the fondness and admiration the actress has had for Sivakarthikeyan. It is to be noted that Shivani has declared herself to be a huge fan of Sivakarthikeyan on a number of occasions. On the work front, Shivani, who made her acting debut in the Vijay TV serial Pagal Nilavu, which aired for three years, subsequently participated as a contestant on Jodi Number One Fun Unlimited in 2018 and came in as the Third runner-up. She was then cast in the Zee Tamil serial, Rettai Roja, but left the production after starring in a few episodes.
