Elle shared a beautiful video, where it’s just the two of them, dancing and hugging at what looked like a birthday party, and the sisters looked genuinely content and happy. “Our song. Your birthday. My sister,” Elle wrote, tossing in a couple of party emojis. Then she added, “She is the coolest person anyone will ever meet and I’m the lucky one who gets to call her mine! I love you @dakotafanning.”Dakota didn’t hold back either. She jumped in the comments with, “Love you the most!!!!!” And on her own feed, Dakota posted a throwback baby photo: her tiny self in front of a birthday cake, wishing for something special. Elle slid into the comments with, “Love you more than anything.”Seeing these photos, videos, and comments, anyone could just feel the love between them.
