She's basically a wannabe wrestler. The saga of Eve Berrington is just parts sad, shame and unabashedly lying to gain followers, attention, and anything she can from anyone who might believe she's talented at anything.
She kind of saw that if she hyped herself on social media enough and is a solid 5 with some dumb tattoos, she could possibly fool people into thinking she's an athlete. She's gone to the US Open for the better part of the last decade, usually on somebody else's dime, and has never won a match, much less scored a single point. The high/low light of this was when she hired or scammed a camera crew into following her around for a documentary when she was at the open one year, where she wrestled like a combined 40 seconds in both of her matches. The reality is she would be a scrub on the JV level of wrestling. She's like August in a lot of ways because if anyone says anything bad about her, people, like what happened here, will come defend her.
If you listen to her bio or read it, she says she got her start doing underground fights, but the truth most likely is she did girl on girl "wrestling" videos for money.
If you search for "Eve Berrington wrestling" on YouTube you'll probably find the match she lost by tech fall to Mallory Velte in 10 seconds.
So that's a pretty basic explanation of who Eve Berrington is.
