Khloe Kardashian and Tristan Thompson are taking legal action against a woman who claims the National Basketball Association player is the father of her child.
Khloe also called out people who were trolling her over the rumours, saying, "The nasty things you're saying about me over A RUMOR!"
Alexander wrote in one caption on Instagram: 'I am extremely upset with LB genetic DNA testing with the fat that they are trying to sabotage a DNA test with Tristian [sic] Thompson regarding my son that he has been neglecting since birth I know for sure that Tristan Thompson is the father of my child'.
The letter also alleges Alexander has defamed Khloe by claiming she has paid people off to shut them up, as well as Tristan.by claiming he's a deadbeat dad. "Including my uterus. Sick". I have seen many hurtful/despicable stories and tweets about me over a false story. "They are co-parenting and giving True an opportunity to have both parents in her life at the same time".
For the unversed, the speculation initially began after fans noticed that Khloe had been taking measures to hide her stomach in Instagram photos and wore baggy clothes.
She ultimately decided against the idea, in favour of freezing her eggs, but on Wednesday, the exes hit headlines after it was claimed Kardashian was pregnant with their second child. News confirmed that Khloe and Tristan had split, amid cheating rumors involving Kylie Jenner's BFF, Jordyn Woods.
"Funny how picky&choosy some can be with who and how you feel others should live their lives", she added. "I believe people should focus on their own lives/families, put energy into bettering the scary world we are now living in, and try projecting positivity as opposed to nastiness.", she tweeted.
The gossip sparked a backlash online, with numerous negative remarks aimed at Kardashian, who was branded a "clown" and a "loser" for appearing to have fallen for Tristan's charms again.
Although the Good American mogul has said it is a "false story", Kardashian has previously touched on the idea of expanding her family during a recent episode of her family's reality series, including the possibility of Thompson, 29, being a sperm donor, according to People magazine.
