Jessie Cave (Lavender Brown)
What she looked like then: A Disney Channel star
What she looks like now: Your friend’s cool mom who wears rompers and knows what memes are
Jessie Cave is a treasure. She hasn’t done much by way of film acting since Harry Potter (although she did play Biddy in Great Expectations in 2012), but she has done a lot of TV in the UK. She has two kids whose pictures are all over her Instagram as well as a YouTube channel where she does comedy sketches. She also released a book of cartoon doodles, which are irreverent and delightful.
