With people across the world isolating, indulging in a bit of nostalgia is completely understandable. So, it makes sense that the next thing to take the online world by storm is the #MeAt20 challenge. Similar to the 10-year challenge that had people posting pictures of how much they looked in 2009 versus 2019, this trend has everyone from sports stars to celebrities posting images of “the good ol’ days” – specifically when they were 20 years old. Want to take a little walk down memory lane? Here’s a look at some of our favourite celebrity throwbacks. This celebrity food writer and chef basically won the Internet over when she posted a black and white photo of herself looking every bit as glamorous as she usually does. As she noted in her tweet, she’s not exactly 20 here but 23 – but who cares about technicalities when you get this blast from the past from Nigella Lawson? Who would have ever guessed that this 20-year-old in a sleeveless leopard print would go on to become a Golden Globe winner? Hugh Grant shared this picture of himself – taken before he went on to become a household name, of course. This actor, comedian and singer is best known for voicing Olaf in <em>Frozen</em>. Admittedly, he seems to have undergone quite the transformation since this photo was taken (including completely changing the colour of his hair). Just one of the many reasons it's hard to link this to the Josh Gad we know today. The<em> Freaks and Geeks</em> actress shared a picture of her 20-year-old self with the scathing question: "Do I win something?". Well, not really, but Busy Philipps did prove that the rules of ageing don't seem to apply to her. Dressing up like someone else is all in a day's work for most actors. <em>Hamilton</em> star Lin-Manuel Miranda did the world a favour by posting a picture of himself in costume aged 20. Here's a look at him dressed as Jennifer Lopez. The British media personality jumped on to the online trend by sharing a photo of herself snapped in 1981, featuring a head full of curls. Carol Vorderman showcased her fresh-faced look from her graduation. Meanwhile, several Indian celebrities also took to sharing their youthful looks. Recognise this former Indian cricketer? It’s none other than Virender Sehwag. Actress Tisca Chopra, 46, chimed in by sharing an old photograph of herself, captioning it “#MeAt20 and also apparently chemical-free”. Meanwhile, actor Ali Fazal posted a school picture brimming with nostalgia.
