Recently, Beyonce has destroyed Rihanna and Mariah Carey has done the same against Fergie.
Those catfights were the previous to this fight and their reasons were only to determine who would be the main bitch in this tag team fight.

Who wins Mariah and Fergie or Beyonce and Rihanna?
I guess that Mariah Carey would assume the main role and Beyonce would do the same, so they would catfight between them while Rihanna would go on Fergie.

By the way, who are the prettier and sexier girls?

[JimmyBondi]

Rihanna and Mariah Carey are the prettier and sexier girls. 

[DoubleJ]

No contest. Fergie IS the hottest AND sexiest of the 4.

[raker]

Jay Zs girls kick some serious ass here...

Fergie finishes Rihanna off quickly and Mariah takes somewhat longer before smothering Beyonce into submission.

i think this wil be great match, Mariah and Fergie will win with my opinion

Beyonce and Rihanna kick asses Mariah and Fergie.  
Beyonice sitting on stomach or back, pulling hair and punching Mariah. Poor Mariah kicking up. -  Particularly this view would be for me interesting.

I think Mariah wins Beyonce and them she helps Fergie to beat Rihanna
