Kris Jenner has shared her daughter Kourtney was "frustrated and felt under-appreciated", before confirming the 40-year-old would be returning to the family's reality show.
Kourtney, who shares sons Mason, 10, and Reign, five, and seven-year-old daughter Penelope with ex Scott Disick, announced she planned to scale back appearances on the show to spend more time being a mom to her children.
However, Kris confirmed during an appearance on The Ellen DeGeneres Show Kourtney was "filming again", after confessing the star had "hit a wall" with the show.
"I think she just needed a bit of a break. You know how we all hit a tipping point, and she hit a wall," Kris explained.
"She was frustrated and she felt under-appreciated and her sisters didn't appreciate her boundaries, so I think after taking a little bit of time off, she's seen the light."
While Kourtney has returned to the fold for the show's 18th season, which debuts Thursday night, in a trailer for the show she's seen engaging in a physical fight with sister Kim, as she and sister Khloe accuse her of having "an attitude".
