It seems Beyoncé knew we'd need almost an entire year to prepare ourselves for her final 2018 Halloween costume . In honour of her 38th birthday earlier this month , the singer reflected on the past year by posting a treasure trove of photos to her website . These pictures include vacation snaps, behind-the-scenes shots from private events, and Leonardo DiCaprio's birthday party — casual. However, the photo people really care about is tucked in with the rest of her Halloween content, and it includes Sir and Rumi Carter.
