Prabhu Deva happy for Dhanush

Choreographer-director Prabhu Deva is happy for southern actor-singer Dhanush, who is making his Bollywood debut with "Raanjhnaa".

"Dhanush has already proved himself and my best wishes are always with him. Now he is in Mumbai, and I am sure he will rock," Prabhu Deva said recently.

Dhanush, who became immensely popular with the song "Why this kolaveri di", features opposite actress Sonam Kapoor in "Raanjhanaa", directed by Aanand L. Rai.
