Ya can't cheat on someone if you're not together anymore ... that's what Victoria's Secret model Josie Canseco is saying after getting tips about Mike Stud hooking up with chicks behind her back.
Here's what we know ... Josie began dating Stud in 2015. He put her in one of his music videos (wearing nothing but a bra and panties, straight FIRE!).
Josie's dad Jose Canseco famously threatened to shoot Mike if he mistreated his daughter -- but they eventually all hung out and got along.
But the couple hit a rough patch in 2018 and after trying to work things out, they eventually decided it was best to part ways.
