Kourtney Kardashian was inspired by her mom, Kris Jenner, when posting a nude picture of herself.

Kardashian posted a picture that showed how her pose was just like her mother's.

"I got it from my mama," she said of the picture.

Kardashian didn't explain when the picture was from, though some speculated that it was one of her pregnancies from her first marriage, as she was sporting a mullet, though others said the hair was actually just pulled back.

Although Kardashian is in a similar post as her mom, the pictures have a few differences. Mainly, Kardashian is showing a bit more skin and places one of her hands on her baby bump. Jenner uses both hands to cover her breasts.

The Huffington Post gave a little more information on Jenner's pose. The picture was taken in 1987, when she was pregnant with Rob Kardashian. She posted the picture to her Celebuzz blog for her son's 25th birthday in 2012.

Kardashian is currently pregnant with her third child. Her other children are Mason, 4, and Penelope, 2.

The oldest Kardashian announced her pregnancy on "Keeping Up with the Kardashians."

In a teaser for Sunday's episode, Khloé and Kourtney Kardashian are seen arguing about money. The two were walking through her new home, which Kourtney was helping her design.

"All we have left to take care of is I just need to have my check sent," Kourtney said.

"The $25,000, you must be out of your mind," replies Khloé. "Get over yourself."

In the video, Kourtney adds that she can't believe her sister would think she would do work on her house without getting paid. Khloé was upset, because she's been with her sister every step of the way.

"What work?" she said. "I've done everything with you."
