PIX: Arjun-Mehr, Shah Rukh, Salman at Sussanne's store launch

Little less than a week after the news of her impending divorce from star husband Hrithik Roshan was made public, Sussanne Roshan stepped out for the launch of her new luxury retail boutique Bandra 190 in Bandra, a western Mumbai suburb, with partners Seema Khan and Maheep Kapoor.

Addressing the rumours of good friend Arjun Rampal's involvement in the split, a stoic Sussanne said at the do, "It's not right to blame anyone for this. We are very close friends.

"You just have to take a call sometimes and there needn't be a 'reason,' it's just a situation we find ourselves in. I can't talk about it clearly; I'm also a mother and a daughter."
