AceShowbiz - With their first child's arrival approaching, soon-to-be parents Khloe Kardashian and Tristan Thompson are said to be having something up their sleeves. Rumor has it, the couple is planning a "Keeping Up with the Kardashians" spin-off once their baby girl is born.

"Khloe and Tristan have been discussing forming their own 'KUWTK' spin-off," says an entertainment insider to HollywoodLife.com. The source also notes that the planned series will be "a completely different concept than her prior show with her ex-husband Lamar Odom," who starred alongside Khloe on "Khloe & Lamar".

According to the report, "the show would basically film during the NBA off-season and would chronicle Khloe's life as a mother." The source adds, "Tristan would also be included in the franchise as well. Tristan is an absolute character, and he would love to be able to show the world his personality and his daily life off the court as well as his dynamic with Khloe."

The Good American designer is also said to be excited as she will have more power on the final edits. "The thought of being able to create something tangible and entertaining with Tristan is a huge draw for Khloe and with it being their show, she can dictate how much of their child will be shown," the insider goes on explaining. "Khloe thinks people will be really interested in her transition into motherhood, and wants to share some of that with her fans."

Khloe and Tristan announced that they're expecting their first child together in late December. In addition, the pair were said to hold an extravagant wedding which costs $2 million at a "private state in Bel Air" during the summer of 2019. It was also said that the reality TV star has asked her baby shower planner Mindy Weiss to help her plan the wedding. "She and Mindy are already going over mood boards and talking about Khloe's vision," a source noted, adding that there would likely be "about 150 people" invited to her nuptials.
