Dhanush's Kolaveri Di that took the entire nation by storm has competition now. And, it’s none other than Sonu Nigam’s son Nevaan, who’s giving him some tough time. The four-year-old’s version has some different lyrics. While Dhanush's song is called Soup Song, Nevaan calls his version Milk Song.

"Oh my god I'm in love with Nevaan's version of Kolaveri. Great idea Sonu Niigaamji. It's very touching and endearing. Hi 5 nevaan. God bless(sic)," Dhanush posted on micro-blogging site Twitter.

Reverting to Dhanush's compliments, Sonu tweeted, “Thank u @dhanushkraja ji... He so loved the song that we thought we should do this for him... And now he thinks you'll meet him :) More Power!(sic)"

Dhanush responded by tweeting, "@sonuniigaam he is a Rockstarji. Would love to meet him and also make a video with him. I know he will steal the show. Still... God bless(sic)."

Sonu concluded by posting, “@dhanushkraja He'll be so happy to meet u... He has emulated ur style so enthusiastically afterall... @dhanushkraja Thank u for giving our nation such an endearing treat of a song... God bless(sic)."

Now, that’s what we call a mutual admiration society!
