Southern actress Samantha Ruth Prabhu is so busy with her projects in hand that she has decided not to sign any new film this year.

`I haven't signed any new film. (I) will not be signing any new film this year. Too much work already, ` posted Samantha on her Twitter page.

The 26-year-old currently has four Telugu projects in her kitty. At the moment, she is busy juggling between Naga Chaitanya-starrer political-thriller `Autonagar Surya` and Junior NTR-starrer action-drama `Ramayya Vasthavayya`.

She is also paired with Mahesh Babu in a yet-to-be-titled action flick. This will be her third film with the Telugu superstar.

Then she has V.V. Vinayak's directorial project in the pipeline.
