According to the source, Khloe and Tristan aren't ready to go public again yet, for fear of being judged.
“It’s a secret because she knows how much everyone would judge her.”
“But she loves him despite how sh***y he treated her.”
Khloe and Tristan split in early 2019 after he was caught cheating on her with her little sister Kylie Jenner’s best friend, Jordyn Woods.
However, could the fact that Jordyn recently passed a lie-detector test have influenced the mum-of-one to give her ex another go after it was proven the pair didn't hook up?
Other clues of a reconsiliation between Khloe and Tristan are striking.
Khloe recently posted a lengthy statement about wanting "peace" from it all, and admitted that she has forgiven both Tristan and Jordyn.
"I'm seeing a lot of commentary about last weeks episode of keeping up with the Kardashians," Khloe began, after it showed Tristan Thompson picking out a diamond necklace as a gift for Khloe.
"As much as I hate speaking on all of this because I'm sure everybody is so over it, as am I, but i'm frustrated that people try to create something that's really not there," she continued.
She went on to say: "I don't hold any negative or hateful feelings toward ANYONE!! I mean that. Life is short! We are all humans trying to figure out this thing called life."
"Who am I to condemn anyone else? Yes, I'm allowed to feel hurt and pain. It would be unnatural for me to pretend as if I don't. Personally, I don't want to be carrying around a hateful heart. I crave peace in my life. Me holding onto hate is only going to hurt me in the end."
She said she does not want to "pollute" her heart and is "allowed to forgive" as she reminded her fans: "Forgiveness is a strength and not a weakness."
Ending her post she said: "I crave peace and happiness in this new year and forever after."
