Kourtney Kardashian Weight Loss: Reality Star Shows Off Slim Figure, What is Her Secret? [PHOTOS]

Kourtney Kardashian is clearly feeling confident after revealing that she is down to 116 pounds, six months after giving birth to her third child Reign.

The mom-of-three looked very stylish as she visited the DASH store in Los Angeles' trendy Melrose Avenue to check on business.

She arrived one day after celebrating her niece North West's 2nd birthday at Disneyland.

Kourtney showcased her enviable post-baby body, giving fans a cheeky glimpse of her toned torso in a black jumpsuit with cut-out sections on both sides.

The 36-year-old wore her dark tresses in a straight, sleek style for the trip and accessorized with a pair of retro, reflective sunglasses.

She boosted up her 5-foot figure with some Stella McCartney platforms while carrying a Givenchy clutch bag with a Bambi pattern.

The reality star was later joined by her sister Khloe, who wore an all-black outfit, long-sleeved top, ripped jeans and studded ankle boots, and had her blonde hair in big and bouncy curls.

Kourtney has been vocal about wanting to shift some post-baby weight after welcoming her third child back in December.

"I think I forget every time - you give birth and you want your stomach to be flat again. It does take a lot of work. Now I'm in full force," she told Harpers Bazaar in April.

Life & Style revealed that 'She jumped on the treadmill and lifted weights to get toned,' a source said of the 36-year-old. 'And she drank a special kind of tea.'

Kourtney is drinking a detox tea called Lyfe Tea Teatox twice a day. 'It clears the body of toxins and gives her energy to work out,' the source explained.

'Kourtney's never lost the baby weight this quickly before,' said the pal. 'She's ecstatic.'

'She's pretty much at her goal weight,' the friend said. 'She says the third time - or baby - was the charm.'
