Well don’t get so excited because Kajol is doing only a special appearance in the movie. Both of them are not paired. Its only a song where Kajol will make her presence for one of the verses, just like the way she made it up in ‘Kabhi Alvida Na Kehna’. The setting of the song will be a Punjabi event and her appearance will be there just for few seconds before the song ends. The song is filmed on SRK and newcomer Anushka Sharma.However, it was Aditya Chopra’s idea to rope in Kajol and all it took was a phone call from Aditya for her to say yes.
