The actor congratulated Prajakta for her successful journey in the virtual world when the duo met on Thursday.
Prajakta, a former radio presenter, is busy with her channel, managed by One Digital Entertainment (a digital video and creator network).
"I'm totally floored with this beautiful surprise orchestrated by One Digital Entertainment's Gurpreet Singh and Sudeep Lahiri who are the ones instrumental in making my birthday wish to meet Hrithik come true," Prajakta, who turned 23 in June, said in a statement.
She added: "I'm super ecstatic that my role model has appreciated my work. If given a chance I'd love to collaborate with Hrithik one day on my channel."
According to a source, Hrithik was receptive to Prajakta.
"He also agreed to subscribe to her channel and give her feedback when Prajakta expressed her desire to work with him since most of her videos have a mention of Hrithik in it," said the source.
On the professional front, Hrithik will next be seen in "Kaabil", and will soon start working on fourth instalment of the popular science-fiction superhero franchise "Krrish".
