Actress Priyanka Chopra is back in Mumbai, after having attended boyfriend Nick Jonas’ music concert in Singapore. Priyanka is shooting her film ‘The Sky is Pink’ which also stars Farhan Akhtar and Zaira Wasim and is based on the real-life story of Aisha Chaudhary, who became a motivational speaker after being diagnosed with pulmonary fibrosis at the age of 13. While Zaira will be essaying the role of Aisha, Priyanka and Farhan will play her parents in the movie. In her personal life, with the media speculating on whether she is engaged to Nick or not, Priyanka has gone on record to say that she doesn’t “owe anybody an explanation”. Yet being the good sport that she is, the actress recently showcased a picture of herself at the gym which has garnered a whole host of excited/cynical reactions. After spotting the picture on Instagram, colleague Ranveer Singh couldn’t help himself from commenting: “PC working out? Now I’ve seen everything...what are you eating post-workout? Chivda?” To which Priyanka instantly replied: “@ranveersingh lol! Nahi yaar! I’ve learned focus and dedication from you!” Seems like Priyanka hardly ever showcases her workout pictures and most people imagine that she gets her ultra-fit looks from a super healthy metabolism. Now we have now way of knowing for sure whether that is fact or fantasy?
