Nothing is wrong with being the "Beyonce" of the group. Gabby is the "Rihanna" .
Rebel haircuts and colors. Modelish face and mess.
They all have their own "thing"
Like Vonc said; in other songs other girls will get shine.
I think it was just a safer bet to Go with Kristal's song where she shines the most because she's the most experienced right now and has the biggest following on her own.
Wouldn't be surprised if the next single is Brie or Ashly heavy
