Tristan Thompson’s mistress and third baby momma is speaking her truth.

Maralee Nichols welcomed a baby boy last week and she alleges Tristan is the father.

The two had an affair in March around his 30th birthday which is when she got pregnant.

She took to Instagram on Monday, December 7 and spilled some hot tea!

Transparency and honesty was all I ever asked for. The love we made… The intimacy… and me opening myself up to you and showing my vulnerability… was all a mistake. Never again.”

The second story slide included, “I never asked you to leave Khloe. Those were your own intentions with no influence on my part.. AT ALL. Let’s make that clear.”

“I won’t allow you and the Kardashians to continue to live behind this façade and “perfect” lifestyle… when that is not the case at all.”

Nichols promised people will know the “dark truths.”

Neither Tristan nor Khloe have publicly commented on the matter.
