Last seen in Barfi!, Priyanka has been juggling time between her musical career and Bollywood and apologised to her fans for not being regular on Twitter.
"Sorry I disappeared... Had to deal with some trash... But back! Thank God for small mercies... last day on Zanjeer... let's go," the 30-year-old tweeted.
The remake of Zanjeer also features Ram Charan Teja and Sanjay Dutt in lead roles.
