Actress Raveena Tandon has opened up on her offscreen bond with her `Karmma Calling` co-star Varun Sood, and shared how during the breaks, they cracked jokes, chatted and laughed with each other. While the onscreen mother-son duo -- Raveena and Varun have some underlying tension in their relationship, their offscreen bond is completely the opposite.

Calling Varun a really sweet guy, Raveena said, "I met him for the first time when we were doing readings with Ruchi. He was very reserved and quiet. I think he was a little nervous, but eventually he opened up. He is a very dedicated actor and knows his craft well."
