Somehow these two are still going strong!

Kourtney Kardashian and Scott Disick joined Kourt's sisters Khloe and and Kendall for lunch at The Villa in Woodland Hills, Calif., on Tuesday. The 36-year-old has slimmed down to a mere 116 lbs after giving birth to her third child, Reign, just six months ago. Wow!

The oldest Kardashian showed off her post-baby body in a pair of super tight ripped white jeans, an off-the-shoulder top and suede sandals. She jazzed up the outfit with a bold patchwork clutch Her main squeeze, who seems in good spirits despite his reported substance abuse issues, looked casual in a plaid shirt and grey jeans.

Khloe, who also joined the couple, emerged from the restaurant wearing a little black halterneck dress and black peep-toe booties.

Kendall rocked her model body in model-slim in black jeans and sheer black lace embroidered and a pair of black jeans.
