Looks like the team of Ajith's flick with Vishnuvardhan is busy celebrating Holi in Mumbai well before the festival.
We hear that Ajith, Arya and Nayanthara are presently shooting for a Holi song in Mumbai on a lavish set.

A source close to the project reveals, "This song will feature at a crucial point in the film, and will lighten the mood before an intense sequence. The unit started shooting this song, composed by Yuvan Shankar Raja, a couple of days ago. The lyrics is in both Tamil and Hindi, and the visuals will have a rich tone. Dinesh master is choreographing this number, which will be a racy one. Only a song and a two-day climax scene is left to be shot in this flick."

The source tells us that the unit had plans of releasing the song this month, coinciding with the actual Holi celebrations across India. "But the filming process was delayed a little as they had to get permission to shoot the number," the source adds.
