Bollywood's multi-faceted talent Farhan Akhtar is gearing up to hit the right notes with `Rock On 2!!`, but for him, tennis star Sania Mirza is the real 'rockstar'.

When the tennis star wished him good luck for his shooting schedule for the sequel of 2008 Indian rock music drama in Shillong, Meghalaya with a tweet `@FarOutAkhtar Gooodd luck Farhan`, the actor responded: `@MirzaSania thank you rockstar.`

Written and directed by debutant filmmaker Shujaat Saudagar, "Rock On 2!!" will see Farhan, Arjun Rampal, Purab Kohli and Prachi Desai reprising their roles from the original film. Actress Shraddha Kapoor is joining the star cast to play the lead role along with Farhan for the first time.
