Varun, 27, and Yami, who star together in crime drama 'Badlapur', visited Kamla Nehru College here to raise awareness about exercising voting rights.
"You all don't realise its (voting) importance right now, but trust me when you all are are older and married and have beautiful children then you will realise how important it is.
I am just trying to do my duty," Varun told the students, who were ecstatic to have the young actor in their college.
Yami added, "You are young girls... you are our future."
The Delhi Legislative Assembly election will be held on February 7. The results will be announced on February 10.
Varun and Yami then read out the election pledge to the young girls, who repeated after them.
"I have never done something like this. Let's do it together. I am going to read out the pledge and you have to repeat after me," said Varun, who is the son of Bollywood filmmaker David Dhawan.
The duo also visited Ramjas College.
Besides Varun and Yami, 'Badlapur' also stars Radhika Apte, Nawazuddin Siddiqui, Vinay Pathak, Divya Dutta and Huma Qureshi.
