I agree with iamrodgers, Mila's dirty tricks would prevail in a NHB catfight. I reckon she's got much bitchier nature then the cute Selena. Then again, Selena's looks indicate she couldn't hurt a fly let alone another girl in a catfight.
Selena would stance more chances in a sanctioned combat like boxing. I can imagine Selena hurting Mila with some crisp hooks to the midsection before sending her down with a uppercut to the chin!
All in all, catfight for Mila, boxing for Selena
