Last week was a historic one with Prime Minister Narendra Modi declaring a 21-day nationwide lock down in India in view of the spreading COVID-19. While people had been home since Saturday anyway, this announcement brought in a more serious message from the government, warning the citizens that it was no time for any relaxations in any laws now. Celebrities who had been doing their best to create awareness among their fans on social media have now started actively making and sharing videos and pictures, pleading with their followers to be home. With home work out tips to various ways of spending time at home, celebrities have been doing everything they can to keep people at home. And the only way to do this is by posting on their social media handles. From Katrina Kaif to Karan Johar, here are celebrities who shared videos and pictures that went viral this week.
