The former couple already share a 4-year-old daughter, True, and their new addition is expected via surrogate any day now.

“We can confirm True will have a sibling who was conceived in November,” Khloé’s spokesperson said at the time. “Khloé is incredibly grateful to the extraordinary surrogate for such a beautiful blessing. We’d like to ask for kindness and privacy so that Khloé can focus on her family.”

Needless to say, people were stunned by the news, as Tristan had been involved in a paternity scandal just eight months ago, when he welcomed a baby boy, Theo, with personal trainer Maralee Nichols.

According to the timeline, Khloé and Tristan’s surrogate was impregnated just weeks before the scandal broke, but this means that Tristan was well aware of the baby already on the way as he planned his new addition with Khloé.

In fact, according to Maralee’s allegations, Tristan was actively encouraging her to have an abortion while simultaneously going forward with the surrogacy plans.

To take it back to the very beginning, Tristan and Khloé first started dating in 2016, but their relationship has been consistently dogged by his infidelity.

Videos of the NBA player cheating on Khloé throughout her pregnancy emerged online in the days before she gave birth to their daughter in April 2018.

This time, Khloé did call the relationship off, and the following year, she began to explore freezing her eggs, as she planned to give True a sibling at some point in the future.

In addition to True and Theo, Tristan shares 5-year-old son Prince with his ex-girlfriend Jordan Craig.

In a 2021 episode of Keeping Up With the Kardashians, Khloé revealed that she’d consider surrogacy for future children because she faces a “high risk of miscarrying” due to the low levels of progesterone in her body — a hormone that is vital for stabilizing the inner lining of the uterus.

Khloé started freezing her eggs in April 2020 and later revealed that she’d chosen Tristan to be a sperm donor after her doctor told her about the benefits of freezing embryos rather than eggs on their own.

Tristan also hints at their impending surrogacy journey as he says: “I’ve always wanted four kids; I have Prince and True so two down, two more to go.”

In the legal filings, released in December last year, Tristan revealed that he first met Maralee in “late November/ early December 2020,” which would have been shortly after this clip with Khloé was filmed.

And while it isn’t known when Khloé and Tristan officially decided to give their relationship another go, they went public with their romance in March 2021.

But, as anybody who keeps up with the Kardashians would be aware, Tristan ended up leaving the lavish birthday party that Khloé threw for him on March 13 to receive a “birthday surprise” from Maralee in Texas.

Tristan had sex with Maralee that night and the following morning, and while he originally claimed that he’d only slept with Maralee those two times, court documents that were published on Dec. 15 saw him concede that they’d had sex “sporadically” for months before his birthday.

“[Nichols] told me that she had been involved with other athletes and understood the limitations of our relationship; to wit, that we might see each other on a sporadic basis for consensual sex only,” he wrote in the filing.

Khloé was not aware of Tristan’s arrangement with Maralee as she pushed on with her surrogacy journey in the spring of 2021.

Unbeknownst to Khloé, at around the same time Maralee would have discovered that she was pregnant with Tristan’s baby.

In the December court documents, Maralee shared alleged messages from Tristan where he told her that he’d have “zero involvement” in raising the baby while appearing to offer her $75,000 to have an abortion.

A follow-up added: “It’s Texas so it will be only a couple hundred dollars, so you better off taking this 75k I’m offering cause you won’t get nothing near that with having a kid with a father who’s unemployed.”

While all of this was going on behind the scenes, Tristan and Khloé’s relationship ended once again in June 2021 amid reports that he’d been seen entering a bedroom with three women at a party in Los Angeles.

A source told E! News that Khloé had broken things off after Tristan “lost all of her trust and the relationship could not be repaired.” They also claimed that Khloé “really tried” to make the relationship work this time around but “felt too betrayed,” was “done,” and would “not go back.”

Khloé echoed that marriage was their “end goal” and that she was excited to “get out of that toxic place [they] were in.”

While it wasn’t mentioned on the show, it appears that the on-again, off-again couple picked up where they left off in their surrogacy process after getting back together. It was confirmed that the embryo was implanted in the surrogate in November 2021.

At this point, Tristan was embroiled in a secret legal battle with Maralee after she filed to sue him for child support and pregnancy-related expenses.

Tristan’s response to Maralee was filed in a legal declaration in December 2021, and he admitted in the paperwork that he’d had sex with Maralee nine months earlier.

He believed that his declaration would not be made public, and he appeared to have no intention of telling Khloé about Maralee or Theo, who was born that same month.

Despite this, it seems as though Khloé’s sisters didn’t know that a surrogate was already pregnant with her and Tristan’s embryo at this point, with Kim referencing the fact that Khloé wanted to have a little boy.

One month later, Maralee’s representative claimed that despite his public declaration, Tristan had “done nothing” to support their child and had “not made any attempt” to meet his son or provide any financial assistance.

After news of their second baby broke, sources revealed that Khloé and Tristan “have not spoken since December outside of coparenting matters.”

On Tuesday, Khloé returned to social media for the first time since the news broke, sharing photos of herself and True on holiday. In a sweet tribute to her daughter, she captioned the post: “Me and my best girl making the best memories. I will forever have your back my angel girl 🤍”

And while she didn’t say anything on her own social media accounts, Khloé did acknowledge the situation with Tristan by liking a fan account’s post that defended him being out with other women.

The post’s caption said that “Khloe and Tristan are both single” and later added: “I don’t know why it would be crazy for Tristan to be with another girl as long as he’s a good dad to his baby.”
