The annual music festival was a family affair with sister, Solange Knowles, performing that weekend as well. Not wanting to miss out on any of the festival and birthday fun, Queen B's mother, Tina Knowles, was also at the festival . Late last night, Knowles shared a sweet photo on Instagram to her eldest daughter saying, "36 years ago God chose me out of all the women in the world to be your mother! How blessed could I be? Not because you are a super talented, smart business woman and one of the biggest superstars! It's because you are the kindest most generous, thoughtful, intuitive, loyal, humble, funny, grounded, grateful and loving human being. I am proud to be your mom. Happy Birthday Baby! I love you with my whole heart.”
