The 67-year-old actor met Khan at his home 'Prateeksha' on Sunday and the two discussed their upcoming movies --'Paa' and '3 Idiots'.

"Aamir dropped by yesterday in the morning at my invitation and it was lovely to spend time with him, discuss the film, show him the promo, receive his appreciation, talk about his own film and invite him for the premiere," Bachchan wrote in his blog.

Khan is awaiting the release of '3 Idiots', which is scheduled to hit theatres on December 25 this year. Both the stars also discussed the promotional strategies for the films.

The team of 'Paa' is racing against time to finish thelast technical details of the film, which will see Amitabh playing a 13-year-old child suffering from progeria, a rare genetic disorder which accelerates ageing.

"Balki (director of 'Paa') wishes that I drop by for a day to have a final look at the background and the mix, before it all goes into print. Our fate now lies in the hands of technicians," Bachchan wrote.

Meanwhile, the Bachchan family is gearing up for Harivansh Rai Bachchan's 101 birth anniversary.
