Amitabh Bachchan upset with Sonam Kapoor - Here's why

New Delhi: Sonam Kapoor just marked her 32nd birthday and the actress was flooded with birthday wishes on Twitter.

Many celebrities took to social media to congratulate the fashion diva on her special day.

While Sonam was busy celebrating her birthday with rumored boyfriend Anand Ahuja in Delhi, the 'Neerja' actress forgot to acknowledge the SMS sent to her by Amitabh Bachchan.

After all the birthday madness got over, Sonam took to Twitter to respond to Suniel Shetty, which made Big B even more upset.

He immediately replied to Sonam's tweet demanding an explanation why he is the only one who didn't get a response.

Check out Big B's Tweet:

... and what about ME .. this is Amitabh Bachchan my dear .. i sent you an sms on your birthday and you never replied ..aaarrrgghh !! — Amitabh Bachchan (@SrBachchan) June 12, 2017

To this, a rather embarrassed Sonam tweeted an apology, explained to the veteran and thanked him for his warm wishes.

This is what Sonam tweeted:

Oh my god sir!! I didn't get it!! I always reply!! Thank you so much! I got @juniorbachchan message  I'm so so sorry https://t.co/AwG4S9W2xr — Sonam Kapoor (@sonamakapoor) June 12, 2017
