Tristan Thompson ‘did have a one night stand in 2012’ with the woman claiming paternity, sources close to the athlete claim.

Kimberly Alexander has a child around four or five years old, so the dates do not line up.

Kimberly hit back on Instagram on Friday saying she didn’t even know Tristan in 2012.

The woman claims that a lab chosen by Tristan, one used previously by the Kardashians, falsified the DNA test he took in January

Tristan and Khloe Kardashian’s lawyer Marty Singer has sent Kimberly a cease and desist letter on Wednesday

The woman has an OnlyFans account, and lists herself as a ‘published model, brand ambassador’ and in ‘Airbnb property management’

But she’s not backing down.
