Birthday celebrations for Tamil superstar and Tamil Nadu Chief Minister Vijay were in full swing as fans, celebrities and political leaders flooded social media with wishes on June 22. But there was one notable absence that became a major talking point online - actress Trisha Krishnan.

Trisha remained silent throughout the day, and as such fans who have followed the duo in a long-term friendship and successful on-screen partnership were not surprised. As hours went by without a public greeting, social media platforms were inundated with questions, theories and discussions as to why the actress had not yet wished Vijay on his special day. The suspense finally ended a day later when Trisha shared a birthday post to Vijay which instantly whipped fans into a frenzy.

What Photo that got everyone talking?

Trisha smiles warmly at Vijay in the now-viral photo, as he stands in front of several birthday cakes. It caught the attention of fans immediately; many focused on the affectionate expression in the picture.

With the picture was a heartfelt message:

"To the one person who makes life worth living. Happy birthday." Besides the caption, fans also noticed another detail. It was a cryptic numerical reference: "00.00."

For the birthday wish itself, however, the mystery number was the topic of great fan discussion.

Fans Rush to Decode '00.00'

Within minutes of the post going live, social media users began trying to understand what the meaning of "00.00" was. Some fans speculated that the number was an indication of new beginnings, others that it meant infinity, completeness or a new chapter in life. A few enthusiasts even associated it with symbolic meanings often associated with spiritual renewal and emotional growth. Others said it could just be midnight, the exact moment Trisha intended to post her birthday greeting.

Despite many theories on the Internet, neither Trisha nor Vijay has provided any explanation on the significance of the number; so fans are free to speculate on it.

'Worth the Wait,' say fans. At the same time the timing of Trisha’s post was also a hot topic.

Many fans had been waiting all day for the actress to publicly acknowledge Vijay's birthday. In the instant after the post came out, there were strong reactions.

"At last, worth the wait," wrote one fan. Another joked about this, “Last wisher ah?” in reference to the delayed greeting they had received.

The comments section soon filled with heart emojis, congratulatory messages and admiration for the duo. Many fans also seemed happy to see the two stars continue their tradition of publicly acknowledging each other’s important milestones. A Popular On-Screen Partnership.

Trisha and Vijay are one of Tamil cinema's most beloved on-screen partnerships.

They have appeared in many big movies together over the years such as Ghilli, Thirupaachi, Aathi, Kuruvi and Leo. Their chemistry on screen has kept them so popular in the public eye that every public interaction between the two is very much watched by fans.

Social Media's Favorite Talking Point

Whether the "00.00" caption was for something more than a picture but personal information that was only known to the two stars remains unclear. One thing is certain, however, that Trisha's delayed birthday greeting generated almost as much attention as Vijay's birthday celebrations themselves.

For fans, the post wasn’t merely a birthday wish to themselves, but a social media event that sparked conversations, theories, and continued speculation that still goes on in the social media space.
