South Superstar Dhanush who made his Bollywood debut with Anand L. Rai's 'Raanjhaana' is all set to do a cameo in his next.

The director who is currently busy with 'Tanu Weds Manu 2' starring R. Madhavan and Kangana Ranaut has apparently asked his good friend Dhanush to make a special appearance in this film.

While the exact details of the same are still being finalised, Dhanush could either be doing a cameo or a performance in a song or who knows, even sing and dance to a song.

The film goes on floors in Lucknow in the month of September this year.
