Abhishek Bachchan broke the Guinness' world record for maximum public appearances in 12 hours while promoting his latest film Delhi 6.

Abhishek Bachchan's whirlwind, record-breaking tour of Delhi and neighbouring cities began two days later than scheduled, but was packed with record breaker chock-a-block post-release flurry of activities.

Abhishek visited the EDM Mall in Ghaziabad, Spice at Noida, Crown Plaza in Faridabad, Select Citywalk, Ambience Mall and Central Mall in Chandigarh and Shoppers' Stop in Juhu in Mumbai.

But at precisely 7.35 pm on Sunday in Chandigarh at the PVR Theatre Central Mall, Tribune Chowk in Sector 29, Abhishek broke the existing Guinness record of German actors Jorgen Vogel and Daniel Brohl in the category of the greatest number of public appearances by a film star at different cities in 12 hours.

Exhausted but exhilarated Abhishek said: "I equalled the existing record at approximately 5 pm on Sunday. How do I feel? On top of the world. It always feels good to do something that goes beyond what's already been done."
