Megastar Amitabh Bachchan has apologised to a "lovely lady", a wheelchair-bound female fan from South Africa, for not being able to meet her.

The 73-year-old tweeted two images featuring the girl in black and red ensembles and holding a note that read: "I am from South Africa. Want to meet you".

"My sincere apologies to this lovely lady for not being able to meet her in the crowd, but will try," tweeted Amitabh, who ensures he meets his fans every Sunday in front of his house here.

The "Piku" star also shared a few images of his fans gathered outside his house.

"My love and my affection to all that make life existing for me," he captioned the images.
