Mumbai:- At a time when marriages and relationships are going kaput in tinsel town, actress-turned-entrepreneur Shilpa Shetty, who believes she has "middle-class thinking" says “discussions” and “arguments” are normal in any marriage. Shilpa is married to businessman Raj Kundra. “I feel that discussions, arguments in any marriage are very normal. But how you get over those and resolve (them), that is important,” Shilpa said on TV show “Yaar Mera Superstar”. Karisma Kapoor-Sanjay Kapur, Hrithik Roshan-Sussanne Khan and Arbaaz Khan-Malaika Arora Khan are a few celebrity couples who have parted ways after having trouble in their paradise. “However you resolve it, you need to make sure you do it within that circle of marriage. That’s why I feel I’m a bit middle-class in my thinking. Trust and respect are very important for a successful marriage. “We should keep the marriage simple and never feel like you’re married to keep the complications away,” added Shilpa, who has son Viaan with Raj. Shilpa and Raj got married in 2009. It was Raj's second marriage.
