Where's the party tonight, Hrithik?

Looks like that after wrapping up work in his upcoming superhero film, Hrithik Roshan finally has some free time on hand. And what better way than to bring in his birthday in style!

The actor who turns 39 tomorrow will throw a bash tonight at his home for his close friends including Arjun Rampal. A source says, "Some of his friends have even taken the day off today to prep themselves up for the party."
