Such a coincidence - GC is also married like SRK was to Gauri. Kajol acted with him in number of hit movies. Kajol is bubbly and lively personality just like KS.
After seeing the pics from SA, it clearly shows their comfortable friendship and chemistry.
Incase anyone is interested, here is SRK and Kajol's interview: http://www.youtube.com/watch?v=ILEkKPgLSvQ
Just thought of sharing.
