The co-founder of Good American, 38, refused to let her unfaithful ex pay for their daughter^/s party in April after she spent all of her hard-earned money and effort organising the lavish event alone.

On this week^/s episode of "The Kardashians," she confessed, saying: "I cannot believe that True is turning 4." She^/s been entrusted to me, and I take that responsibility very seriously. I have the chance to mould her into an amazing young woman, and I^/m not going to take that responsibility lightly. I^/m going to work as hard as I can.

Khloe is informed by Kris Jenner, Tristan^/s mother, at the party that Tristan "privately went ahead and took care of the whole party."

The mother of two, who also shares a three-month-old kid by a surrogate with the NBA player, was unimpressed.
He^/s not managing the entire party, she assured her mother.

Nice try, but I^/m not letting that happen.

Khloe said, "And I^/m really excited that I could do it all by myself," following Kris^/s statement that he was "so excited to do it."

That^/s very sweet, but I won^/t allow him do that, she insisted.

She said, "I work so hard to do intricate things for True and I don^/t need anyone^/s help." in another confessional.

Despite being aware that he was expecting a boy with Khloe, Tristan, 31, fathered a child in 2021 with fitness instructor Maralee Nichols.

The baby was born on July 28; its name is currently unknown.
