Gambhir, who joined the team last evening as a replacement for injured opener Lokesh Rahul, stood alongside Wriddhiman Saha and Ravichandran Ashwin while a padded up Kohli quickly joined them.
The fans witnessed ugly spat between Kohli and Gambhir during the 2013 season during a match in Bangalore.
Today they were seen in a lengthy discussion peppered with some laughs. Drafted into the Test side after more than two years, Gambhir was later seen chatting with team India coach Anil Kumble even as he did not bats long in the nets.
The duo faced only a few deliveries in the fag end of the two-hour practice but skipper Kohli later clarified that no inference could be drawn from the practice session.

Kohli said sometimes the batting order was followed but it is not necessary that people who have not batted for long during the nets, won't play.
"Day before the game we definitely look to do that with the batting order. It can differ from player to player. Sometimes a player doesn't want to bat in the nets. He just wants throwdowns and then walk away.
Gambhir's stint at the two-hour net session also included giving some catching practice at the start to Ajinkya Rahane and Shikhar Dhawan.
