Freida Pinto remembers how co-star and boyfriend Dev Patel once accidentally punched her in the face while promoting "Slumdog Millionaire".

The 26-year-old actress took a blow from Dev while they were promoting "Slumdog Millionaire", the Oscar-winning movie that brought them together in the year 2008. She, however, seemed to enjoy it.

"Small things bring so much joy to us, like when we were first doing interviews, there was one time when Dev punched me in my face by mistake, " femalefirst.co.uk reported Freida as saying.

This accidental punch was one of the many intriguing events that took place on the sets of the movie and the actress believes only she and Patel can understand them.

"The only two people who can understand what happened on 'Slumdog...' are the two of us. Even our families, who appreciate and support us, are still on the outside and that is why we hold it so very dear to our hearts, " she said.
