Nene Raju, Nene Mantri, being directed by Teja, happens to be Kajal's 50th film.
She is thrilled to have reunited with her mentor Teja after a decade.
"It's been a pleasure working with him (Teja) as he encourages me to unlearn the nuances I have picked up over the span of my film career, and to look at my character and this film with a fresh perspective," Kajal told IANS.
She also said that the film, which will simultaneously release in Tamil, Hindi and Malayalam, is her best birthday gift.
Nene Raju, Nene Mantri, produced by Suresh Daggubati, ACH Bharath Chowdhary and V Kiran Reddy, also stars Catherine Tresa, Navdeep and Ashutosh Rana.
