Queen Bey showed off her toned tummy in a cropped Fila shirt and distressed black denim shorts, accessorizing her fierce style with an oversized camouflage jacket, tons of jewelry and a belly button ring.
The "Formation" singer left her newborn twins at home, but enjoyed a little quality time with her firstborn, 5-year-old Blue Ivy, at Lamar's concert. Bey worked with Lamar on her song, "Freedom."
"She's a perfectionist," Lamar recently told Rolling Stone about the singer, adding that she taught him "how to be particular about your music." "Think about the  BET performance. She was very particular -- the lighting, the camera blocking, the transition from the music to the dancing. It was confirmation of something I already knew."
