Celebrity hairstylist Sapna Bhavnani, who grabbed attention with her vocal and fierce behaviour in the sixth season of the controversial reality TV show "Bigg Boss", has taken a dig at actress Alia Bhatt, who was heard talking about feminism on a radio channel. "Just heard aalia bhatt on radio saying shes a part feminist. #lol is she really that duh? What is a part #feminist? #help #WomanEmpowerment," Bhavnani tweeted on Saturday. This is not the first time the "Student Of The Year" star has been trolled on a social media platform. Alia gained attention when she made a goof up in the fourth season of "Koffee With Karan", hosted by filmmaker Karan Johar, where the "Shaandaar" actress said Prithviraj Chavan was the president of India. Ever since then, Alia has become the subject of jokes and trolls on the social media. (Source: IANS)
