The actress is currently dating fellow Bollywood star Kunal Khemu.
Khan told DNA India: "The key to any successful relationship is communication. I believe that talking things out solves most of the problems and that's exactly what I do.
"Not just with your better half, talking about what's bothering you with friends and family members can also help you relax."
Khan added: "I'm definitely a romantic person at heart. When I'm in a relationship, it's all about that special person, but Valentine's Day is not a momentous day for me. I don't celebrate the month of love as such.
"Having said that, both Kunal and I are impulsive people, so we're quite unpredictable."
In January, it was reported that the Soundtrack star had become engaged to Khemu.
The couple began dating in 2010, but kept their relationship secret to avoid intrusive media speculation.
