Knowles formerly worked as both Beyoncé, 38, and Solange’s managers as well as the manager of Destiny’s Child.
Knowles’ relationship with Beyoncé became strained in recent years, but it appears they are now on good terms.
Last month on Sept. 4, Knowles wished Beyoncé a happy 38th birthday on Instagram with a sweet tribute on Instagram.
“It’s your birthday! I hope you party like it’s your birthday, @beyoncé! Love, Dad,” Knowles wrote alongside a video compilation of Beyoncé performing.
Beyoncé also shared heartwarming moments of her life on her birthday to her website.
The twins (who each sat in one of their mama’s arms) wore matching colorful outfits for the snapshot, featuring straps in a green, yellow and red stripe pattern.
“Thank you from the depths of me for all my Birthday Loving,” the “Spirit” singer addressed her fans in a handwritten note, shown above the images. “I had an incredible B-day! I’m grateful for every breath. I thank GOD for all of my Blessings, my wins, and my Losses. I thank GOD for All of you!”
“I would have posted earlier But I had work to do. I gotta job BAAAABY. Here is your B at 37,” she continued, concluding with a hand-drawn heart and, “Love y’all.”
