Sarah was the only one to beat her until Nikki... sadly we never got a rematch between Mila and Nikki.
That’s because Nikki completely kicked her ass and she tucked tail and ran.
Mila was also trying face slapping for the first time In the fight vs Nikki, so it made the ass kicking even worse, especially with the ending, she just completely rained slaps onto her face.
Mila was asked about a rematch, apparently she originally was asking for waaaaaay too much money (ducking technique) then she said she was going back to catfighting after her socials took a dove as most of her fans just wanted to see her fight,
She shot down every recommendation of a fight with Nikki and as far as I’m aware she has never fought again since this point.
