"Sick and lying in bed. Not not not happyy," Parineeti tweeted on Saturday.
However, the actress, who made her acting debut with a supporting role in the 2011 romantic comedy "Ladies vs Ricky Bahl", refrained from sharing more information about her illness on the social media platform.
Meanwhile, 2014 turned out to be a low key year for the cousin of actress Priyanka Chopra. Of Parineeti's three releases -- "Hasee Toh Phasee", "Daawat-e-Ishq" and "Kill Dil", two bombed at the box office.
"Hasee Toh Phasee", which also starred Sidharth Malhotra, had a fair box office performance.
