Amitabh Bachchan, whose daughter-in-law Aishwarya Rai is expected to give birth anytime now, can’t wait to see the new arrival and says he is enjoying the hustle bustle in the house.

“The family gathers together from all over as we wait for the ‘arrival’ … Greatest joy for me – a full house and the ‘chahel – pahel’ (hustle bustle),” the 69-year-old posted on micro-blogging site Twitter.

Aishwarya is expecting her first child with actor-husband Abhishek Bachchan.

Apart from waiting excitedly for the baby, Amitabh also took some time off to watch Ranbir Kapoor-starrer “Rockstar” which released Friday and the actor says he is impressed with the entire team.

“It’s late but not without cause… just back from ‘RockStar’ and living in the brilliance of all – Imtiaz Ali, Ranbir, AR and Nargis… Still with ‘RockStar’ and its beauty,” he further posted.

Directed by Imtiaz Ali, “Rockstar” chronicles the journey of an aspiring singer Janardhan Jakhar, who wants to make it big in the music world. It introduces two new faces – Pakistani-American model Nargis Fakhri and Brazilian model Moufid Aziz.
