Kim Kardashian showed off her slimmed down curves in a sexy Instagram video on Friday, after confessing earlier this week she has lost 21lbs since trying to fit into Marilyn Monroe's dress.
The television personality, 41, looked incredible in a slinky grey dress which accentuated her weight loss as she headed out to dinner with daughter North.
Kim attended the launch bash of her new skincare line SKNN which she documented on her Instagram stories and couldn't resist showing off her outfit.
The mum-of-four wore a long light grey strapless gown which showed her looking slimmer than ever.
She wore her bleach blonde hair in a long plait along and amped up the glamour with a full face of make-up.
Kim's eldest daughter North, nine, matched her mum as she wore a dress of the same colour with matching glasses.
Kim filmed the two of them and said: "She pouted her lips at the camera and said: "My fly girl wearing silver tonight for our SKNN dinner.

"Can't wait to show you how beautiful it all is."
Kim's new line comes with a nine-step kit which includes a cleanser, toner, exfoliator, hyaluronic acid serum, vitamin C serum, and other products.
However the kit comes in at a total of $630.
Kim has come under fire recently as she revealed she had lost 16lbs in just three weeks ahead of the Met Gala.
Since then she has said she's lost even more weight and is now 21lbs down.
She said on The TODAY show : "It actually taught me a lot about my lifestyle and my health, and since then, afterward, I continued to eat really healthy. I mean, I'm down 21 pounds now. I'm not trying to lose any more weight, but I have more energy than ever.
"I cut out so much sugar, a lot of junk food I was eating, I didn't even realize it. A lot of fried foods, and I just completely changed my lifestyle."
The star lost the weight to fit into Marilyn Monroe's 'Happy Birthday Mr President' dress.
She told Vogue on the red carpet: "I tried [the dress] on and it didn't fit me. I said, 'Give me three weeks.'
"I had to lose 16 pounds down today. It was such a challenge. It was like a [movie] role. I was determined to fit [into] it. I haven't had carbs or sugar in about three weeks."
This comes after Kim and her sister Khloe have been accused of getting surgery after appearing to look different in photos.
Some people thought that the pair had removed their BBL (Brazilian Butt Lift), however they have never confirmed that they had the procedure in the first place.
The rumours started after the two of them lost weight but have also been working out and showing off their healthy lifestyles.
