Guess what actor and social activist Shabana Azmi got on her 60th birthday from husband Javed Akhtar - a cake designed as a slum!

This is revealed in his latest tweet by megastar Amitabh Bachchan, who was invited to the bash, where the theme was 'wear a headgear'.

The Big B, 67, who has rubbed shoulders with Shabana in "Amar Akbar Anthony", was present at the birthday bash with wife Jaya, son Abhishek and daughter-in-law Aishwarya.

"At Shabana Azmi's 60th (birthday)... such joy to meet up with old friends and colleagues... and listening to blaring 60's- 70's music... Javed Saheb at his humorous best... in splits with his one liners! Shatru (Shatrughan Sinha), Vinod (Khanna) and I meeting after ages... such nostalgia (sic), " Amitabh tweeted.

"The theme for the party was 'wear a head gear'... I mustered a Manali cap.. many did not comply... Javed and Shabana spiked hair... Javed Saheb's gift to Shabana - a cake designed like a slum!! Touche (sic), " he added.
