Kajol does a cameo for Aamir

After U, ME AUR HUM, actress Kajol will be seen in a Karan Johar film... quite expected, eh? But for some more interesting news, the actor is doing a cameo for another Khan, Aamir! At least that's what the gupshup is these days.

Kads, who makes that extra effort for KJo, SRK or then hubby Devgan, readily accepted to do a special appearance in Raj Kumar Hirani's 3 IDIOTS.

Apparently Kajol has done this role just for Aamir, whom she was paired opposite in FANAA. But what is it exactly that she's doing in 3 IDIOTS isn't too clear yet. It's a small but fantastic role, we're told. Kads?
