Directed by Sanjay Leela Bhansali, the musical love story is releasing on Nov 9 and there are butterflies in Sonam's stomach.
'We need all the prayers right now because 'Saawariya' is not a typical film. Of course, it has loads of songs and dances, but the presentation is so delicately classical. My character is so quiet and withdrawn that we needed eight songs to bring me out,' Sonam told IANS.
The pair visited the temple early Tuesday morning to avoid media glare.
'We went at 5 a.m. for the first aarti, hoping no one would be there. When we reached there were a thousand photographers and fans waiting for us. I've no clue how they knew. I've walked to Siddhi Vinayak before, but not at this time. It's really beautiful out there. I specially loved the aarti,' she said.
Ranbir walked most of the way.
'But I couldn't make it barefoot. I had my slippers. I'd have loved to,' said Ranbir. 'I had my best friend Binoy and, of course, Sonam with me.'
Ranbir isn't a very demonstratively religious person. 'But I've walked to Siddhi Vinayak before. That was when I had got admission in a college in the US. But now I guess I'm going through a much bigger test.'
