The Enola Holmes star shared a blissful photo to Instagram on Wednesday, Dec. 28, where she was seen lounging in the middle of an open, grassy field while flashing a giant smile to the camera.   With her hair pulled back into a casual updo, Brown, 18, sported a cozy look for the outing, wearing a matching white linen set while sitting in the middle of the grass on top of a mattress covered in plush blankets and pillows. In the carefree pic, the sunset is also seen peaking out from the distance, as a golden glow illuminates the entire left side of the frame. “Days like these make me happy 🌅💜” the Stranger Things star captioned the post, which already has over 700,000 likes and thousands of adoring comments from her fans.  But some of her followers couldn’t help but notice a mystery item next to Brown in the photo, which was intentionally blocked out with an emoji.  Some fans speculated that the covered-up item could have something to do with the actress’ beauty brand, florence by Mills, which she tagged in the caption on her post.  She also teased “•lots to come in 2023• xoxo” in the caption, and the emoji used to block out the product was a purple heart, the signature color of the clean beauty brand.  While fans aren’t certain what will come next from the makeup and skincare company, they can surely expect more fun-loving content from Brown, who is always sharing life updates and glamorous photos to her Instagram page.
