Her first post was an adorable throwback of herself as a child, and since then Mendes has posted an almost nonstop stream of photos of herself as well as snaps of different people and things that inspire her. And now, the actress is finally gracing us with her first-ever selfie, and she's doing it for a good cause. "This is my first selfie and it's for an amazing cause! Thank you all so much for helping support Andrew Wilson and his family. Please, please donate - any bit helps! I'm going to sign this tshirt and give it away to one person who makes a donation within the next 48 hours. Click the link in my bio to donate. Together let's help this family get their son the proper treatment that he needs," she captioned the beyond gorgeous snap. Now if only we could get Mendes's tips for taking the perfect selfie.
