Kajol turns 44 on Sunday. As a birthday gift, the trailer of her next, Helicopter Eela, will be launched on her big day at a Juhu multiplex. Hubby Ajay Devgn is the film's producer, while Pradeep Sarkar wields the directorial baton. We guess the drama's first look will be followed by cake-cutting.

Written by Mitesh Shah, "Helicopter Eela" will see Kajol playing a single mother and an aspiring singer. The movie is co-produced by Ajay Devgn and Jayantilal Gada of Pen India Ltd. It is slated to release on September 7. The trailer will be released in the presence of her husband-actor-producer Ajay, and co-star Riddhi along with Sarkar. Kajol described the film as 'sweet and funny'. "It is a sweet and funny film. Riddhi will be seen as my son. We all are very excited about the film."
