Whether we like it or not, celebrities hold much influence over public thought. And when they choose to use their platform to engage with the public positively, minds can change. Tom Hanks used his platform not only to encourage social distancing, but to remind people to register to vote online for the upcoming US election. Other celebs have received far-reaching, and vastly different, reactions to their positive online outreach. Here are some of the most memorable posts so far. Idris Elba This morning I tested positive for Covid 19. I feel ok, I have no symptoms so far but have been isolated since I found out about my possible exposure to the virus. Stay home people and be pragmatic.

Fans of Elba quickly started posting thirsty tweets, saying they’d gladly be quarantined with the hot star and take whatever he is infecting. Erm, not quite.

Isolated in his family home, Kim assured fans he was on the path to recovery and used his platform to thank front line medical professionals for their tireless work while calling racists “cowardly” for verbally and physically attacking Asian Americans. Hate crimes against Asians in the West have spiked recently – a good thing Kim is here to set these fools straight.

Cardi B View this post on Instagram I said what I said A post shared by Cardi B (@iamcardib) on Mar 24, 2020 at 4:42pm PDT Honestly, if she ran the US government, things would almost certainly be better.

Cardi B expressed that she is most concerned for working-class folk and has said that all the proceeds from her recent track will be donated to good causes. Cardi B gets it, why does’t the government? Bill and Melinda Gates Teachers are doing incredible work to keep kids learning while at home.
