Maralee Nichols seemingly shaded Khloé Kardashian as the reality star threw an epic 5th birthday bash for daughter True.

After the “Keeping Up With the Kardashians” alum posted party pics via Instagram Sunday, Nichols documented a beach outing with her and Tristan Thompson’s 1-year-old son, Theo.

“Happiness ????????,” she wrote alongside the social media upload.

“it’s the simple things in life that are the most extraordinary.”

Instagram users commented on the pointed caption, with one writing, “This one will grow up mentally healthy and happy in the natural world.”

Another added, “Simple is right!”

The fitness model’s followers bashed Thompson, 32, in the comments, noting Theo’s absence from his half-sister True’s party.

Nichols gave birth to her baby boy in December 2021, one month after Thompson and Kardashian, 38, conceived their second child via surrogate.

The on-again, off-again couple’s son arrived in August of the following year, and his name is still a secret.

While Thompson initially denied paternity of Nichols’ baby, he confirmed in January 2022 that he is the father — and was ordered to pay $10K per month in December 2022.

A source told Page Six that the NBA player “is paying and has paid child support to Ms. Nichols retroactive to the date she delivered the child,” although he does not appear to have met the toddler.

The athlete did, however, attend True’s party over the weekend.

The epic event featured a ball pit, sno cone carts, customized backpacks and more.

The party took place at Kardashian’s Hidden Hills, Calif., home. Notably, Thompson recently moved into the mansion three doors down.

While the duo have sparked romance rumors since reuniting for Thompson’s mother’s funeral in January, Kardashian clarified earlier this month that she is “single.”

The “Kardashians” star’s relationship status didn’t stop her from gushing over the “best father” in a 32nd birthday tribute on March 13.

“Your love, attention, silly dances, hugs, carpool rides, bed time rituals, the way u show up for them. All of the above means more than you’ll ever know to your family of littles,” she wrote via Instagram.

“My birthday wish for u is that u continue to crave change, healing, and transformation. Be strong, be kind, be patient, be free.”

Thompson is also the father of son Prince, 6, with ex Jordan Craig.
