I feel like Rihanna's all talk with nothing to back it up with. Shakira looks like she could kick some ass.
Maybe Bey could pull some Obsessed like butt whooping. Idk about Gaga.
IDK...I think Shakira could take Gaga. They're both little, but I think Shaki would come out on top. Rih and Bey...Bey. Bey is in better shape, is more muscular and has higher endurance. Plus Bey is quiet...it's usually the quiet ones that end up knocking the paint off a bish, not the ones with all the mouth.
If we swap it out, I think Rih would beat Gaga and I think Bey could take Shakira...they both have a big size advantage over Gaga and Shakira.
