Dhanush's cameo in Maddy's film

Dhanush debuted in Bollywood last year with his outstanding performance in Aanand L Rai's Raanjhanaa. While the director is busy shooting 'Tanu weds Manu 2' starring Madhavan and Kangana Ranaut, actor Dhanush who is busy shooting for his second Hindi film 'Shamitabh' directed by Balki, took time to visit the sets of 'Tanu weds Manu 2'.
While Maddy posted a picture of himself behind the camera and Dhanush calling shots, Dhanush posted a picture along with Anand L Rai says "In Delhi at tanu weds manu 2 sets.With my most favourite Anand l rai :) miss acting under his direction."
We had earlier reported that Dhanush could either be doing a cameo or perform in a song in the film. The star actor joined sets in Delhi today and spent time with the director and actor Madhavan. Looks like he must have shot for his cameo performance in the film.
