Tristan Thompson allegedly knew that he was expecting a baby with another woman whilst he was in the process of having a child via surrogate with Khloé Kardashian.
The basketball player, 31, and the reality TV star, 38 - who were already parents to daughter True Thompson, four - welcomed a son, born through surrogacy, last month.
He had previously welcomed a son, Theo, now 9 months old, with Maralee Nichols in December last year, having slept with her whilst he was allegedly still dating Khloé.
