The actress, who appeared in Priyadarshan's movie De Dana Dan, admitted that she does not know what the role will be but called it the best present she had received.
"I couldn't have got a better birthday gift," she told Real Bollywood.
"I don't need to ask him what it is or in which film. I trust him completely. He gave me a role in De Dana Dan that did justice to my presence."
Reddy has become close to Priyadarshan and his wife Lizzie and reportedly stays with them whenever she is in Chennai.
The couple's anniversary was on the same day as Reddy's birthday so the trio celebrated together at a party at Shristi Behl's house.
