Khloe and Kourtney Kardashian and Jessica Alba were among the famous faces who attended Lopez's concert Sunday night, and their star power-filled Instagram snaps are definitely #squadgoals. Khloé took to Instagram to share a few fierce girl power photos with her 49.3 million followers. The first photo, captioned "Bow down to the queen," shows the Keeping Up with the Kardashian star with sister Kourtney, Alba, Meghan Trainor, Laverne Cox, and of course, the queen J.Lo herself. The starlets are all dressed in arrays of blacks and metallic, and they look fierce.
