Bollywood heart-throb Hrithik Roshan for the first time celebrated his birthday Monday with media by cutting a cake, talking about his future projects and revealing his happiness over his filmmaker father's decision to make a sequel to "Krrish".

"I'm very happy that papa (Rakesh Roshan) has finally taken the mantle and said that he will make 'Krrish' because it was my dream to make another 'Krrish'...I was wishing that one day he gets up and thinks about the film and I'm happy that has happened now, " said the actor, who has turned 37.

The actor also revealed that actress Priyanka Chopra will be the female lead in the film and it is slated to hit screens later this year.

Released in 2006, "Krrish" is a Indian superhero science fiction that carried forward the story of "Koi... Mil Gaya" about developmentally challenged Rohit (Hrithik) and his ability to connect with aliens through his late father's special computer.

In "Krrish", Hrithik plays Krishna, son of Rohit, who has superhuman abilities. Both the films were directed and produced by Rakesh Roshan.

The actor, whose much hyped "Kites" bit the dust at the box office, will be seen in two more films - "Zindagi Milegi Na Dobara" and "Agneepath" remake - this year.

"I'm very excited about all the three films because all are challenging roles. One is over and I'll be starting 'Agneepath' now and then of course 'Krrish', " said the actor who was casually dressed in a white T-shirt and blue jeans and teamed it up with a black cap for the media meet.

Taking about his birthday, the actor said that age is just a state of mind.

"Number and years are all man made terms in our minds. We should not go by them. You're as young as you're heart tells you. I still feel as I felt when I was 18. Although my knees heart a bit more than they used to, " said Hrithik.

The actor started his day with a pooja at home, then spent time with his family, followed by a telephonic session with fans, meeting with media and it will end with a party at his place.
