The actress, who has a leading role in Priyadarshan's Tezz, has recently returned to Mumbai after shooting in Birmingham.
"Every evening when I'd get back to my room, I'd just want to sit in hot water," the star told Hindustan Times.
Reddy, who is rumoured to be playing a negative role in the action thriller, features along Anil Kapoor and Zayed Khan in the project.
"Shooting with them was a breeze,” said the Race star. "The weather was the only problem. It was raining and cold but I'm looking forward to the next schedule in Scotland in March."
Tezz is reportedly a Hindi film adaptation of the Hollywood hit Speed.
