The two are already collaborating on a 3-film deal (Shah Rukh Khan-Karan Johar team up for 3 films, August 6).
And now, King Khan is taking an active interest in KJo's next project too.
The superstar took to Twitter to enquire about Ae Dil Hai Mushkil's shoot in London. What's more, he promised to drop by on Saturday at the shoot.
Don't miss how SRK pointedly mentioned that he wants black coffee. Hmm, that's SRK's idea of Koffee With Karan, eh?
Considering Shah Rukh himself is busy with Dilwale shoot, it's great to see that he doesn't mind taking out time for his close pal Karan.
