Chewing paan and riding a rickshaw, Bollywood superstar Aamir Khan turned 'Banarasi babu' to promote 3 Idiots as he made his first stop in the holy city.

The 44-year-old actor has put on a disappearing act and is on a seven city tour to promote the film. Aamir reached Varanasi on Friday and traveled through.

The narrow lanes of the old city to search his mother, Zeenat's birth place in Teliyanala area, near the Prahlad Ghat at the banks of river Ganga.

Wearing a simple shirt, his face covered with a muffler, Aamir hid himself in old sunglasses. He stayed in the city for three days in the disguise of an old man.

The morning before leaving the city, Aamir reached the Teliyanala mohalla in the Kotwali area to visit his mother's birthplace Khwaja Manzil, which is in a dilapidated condition.
