Kourtney Kardashian Flaunts Weight Loss, Wants To Tell Kids About Bruce Jenner Changes With Scott Disick [Video]

A mere seven weeks after giving birth to son Reign Aston Disick, Kourtney Kardashian has restored her slender figure. And when it comes to those post-pregnancy weight loss secrets, Kardashian is now sharing all her secrets, revealed Entertainment Tonight.

The 35-year-old co-star of Kourtney & Khloe Take the Hamptons has a sense of humor about her occasional wardrobe malfunctions, however. She posted a photo of her recent date with Scott Disick with a self-mocking caption.

As for how she slimmed down so quickly, Kourtney credits waist-training, which involves using an old-fashioned corset that supposedly results in weight loss.

Gettin’ it right, gettin’ it tight…with my waist shaper! #waistgangsociety @premadonna87 @pre_shop

But although she’s perky about her weight loss success, Kourtney is agonizing about how to approach Bruce Jenner‘s transformation with her children, according to Radar Online.

“[They are] struggling over how to explain to their children that their grandfather Bruce is becoming a woman,” said a source.

“The whole family is supportive of Bruce’s transition. But Scott thinks it is going to be a little weird to have to explain to the kids what is going on.”

While Mason is five years old, Penelope is only two. While Kourtney and Scott aren’t worried about the newborn baby or Penelope, they have expressed concern about how to tell their curious little boy Mason about Bruce’s changes, added the source.

“As of right now, Bruce is ‘Pop-Pop’ to Mason and they do not know how they are going to tell Mason Bruce is going to now be a grandma. But Mason is so inquisitive and nothing gets by him.”

As the Inquisitr reported, Jenner’s sons Brody and Brandon have been vocal in their support of his changes.

And when they saw the infamous InTouch cover story that used Photoshop to make their father look as if he had already become a woman, with the headline “Bruce’s Story: My life as a woman,” they expressed their outrage.

“The magazine cover didn’t come as a surprise to the brothers, but they both feel it’s very insensitive to the LGBT community. Both Brandon and Brody are both very strong supporters of LGBT people. They’re standing by their dad through this.”

But Kim Kardashian has taken a different approach to discussing Bruce Jenner’s transformation, as the Inquisitr noted.

“I think everyone goes through things in life,” said Kim. “I think Bruce should tell his story his way [and] share, whenever he thinks the time is right.”
