Shilpa replied: "It's important to have the relationship of friendship in any relationship. I think Raj and I never feel that we are tied to this relationship of marriage.

"Even now we go on dates on Friday nights, we call each other girlfriend and boyfriend. So, we don't want to feel that burden that we are together just because we are in a marriage," she added.

She thinks most marriages fall apart because "they think they have some pressure so touchwood, that's not there between us".

Helping each other as a couple is important for her.

"Trust is also a bedrock of any relationship. It's our 10th year now... It's important to grow in any relationship, be it between friends, siblings or partners, otherwise you outgrow the relationship.

"It's very important for me that I learn from every relationship that I have with people and I have learnt a lot of things from Raj and even you have to keep upgrading yourself," she shared.

Shilpa and Raj have a son, Viaan Raj Kundra.
