Kourtney Kardashian, who is pregnant with a third baby, has posted a naked throwback picture of her taken during one of her previous pregnancies and proudly compared it with her mom Kris Jenner's almost similar nude pregnancy picture. The mother and daughter are both posing completely topless in their pregnancy pictures and hiding their breasts with their hands. Check it out here.

Kris Jenner looks really young in her picture and has a mullet-styled hair (a hairstyle which tapers at the nape of the neck and is short otherwise). It is not sure whom Kris Jenner was carrying when she was pregnant in the picture. Jenner covers her breasts with her hands as she poses sideways for the shot. Her 35-year-old daughter Kourtney has also posted her picture in almost similar pose.

"I got it from my mama," writes Kourtney about the picture. There are two differences between Kris Jenner and Kourtney's picture. One is that of placement of hands. Kris is seen holding her breasts with both the hands while Kourtney supports her baby bump with one hand and keeps the other one on her breasts. Also, Kris Jenner seems to be wearing her pants while posing for the picture back then while Kourtney shows off her bums.

Kourtney is not the only celebrity who has posed naked and flaunted her baby bump during pregnancy. The trend was set by "Ghost" actress Demi Moore in 1991 when she posed naked during her pregnancy for Vanity Fair magazine. Off late, many celebrities have proudly showed off their naked bodies during their pregnancies including singer Christina Aguilera, Victoria's Secret model Alessandra Ambrosio and even Hollywood actress Jessica Simpson.

Kourtney announced her third pregnancy during one of the episodes of "Keeping up with the Kardashians." She already has a two year old daughter Penelope and a four year old son Mason with her partner Scott Disick. The eldest sister in the Kardashian clan is expecting the new baby by December.

Meanwhile, the latest episode teaser of KUWTK shows Kourtney and her younger sister Khloe arguing. Kourthey wants Khloe to pay her $25000 to help her decorate her house but Khloe does not seem to agree to it and says she was very much a part of the entire work.
