One of the chicks Tristan Thompson made out with back in October says she had no idea he was serious with Khloe Kardashian … much less that she was having his baby.
The woman’s name is Marie — she’s the one on the left in the surveillance video — and sources close to her tell TMZ … Marie was given the impression Tristan and Khloe’s relationship was casual. We’re told she later learned Tristan and Khloe had been together for almost a year … and, at that point, she cut off the fling.
According to TMZ, Marie is a mother herself, and did not want to be a homewrecker.
