Yesterday, Parineeti Chopra faced a singer's worst nightmare. A throat infection just a day ahead of a concert for her upcoming film, 'Meri Pyaari Bindu'.The actress makes her singing debut with the film. She posted on social media, "I have woken up with no voice today and I am very stressed because tomorrow is the 'Meri Pyaari Bindu' concert and I have to sing for all my fans." Some well deserved rest to the vocal chords and gargling with warm water might help.
