Kourtney Kardashian rocks a revealing black midi dress, showcasing her fit body after three kids

The sexy reality starccaused heads to turn attending a recent event in a see-through dress with her boyfriend by her side.

Kourtney Kardashian could have fooled anyone thinking she wasn’t a mother-of-three as she paraded her gorgeous body in a revealing black dress, showing no signs of motherhood.

On Friday, May 4, the 39-year-old made a grand entrance at the Syrian Medical Society event in Beverly Hills showcasing her fit physique with boyfriend Younes Bendjima by her side.

Dressed in a black midi dress with fishnet cut-outs revealing her flat midriff and toned legs, the petite stunner easily stole the spotlight that night, according to the Daily Mail. Her hair was swept back from her face and she wore minimal accessories drawing more attention to her captivating look.

Looking dapper next to her as they held hands was her 25-year-old beau who wore a double-breasted navy blue blazer over a white collared shirt and black pants, finishing off his look with a pair of grey New Balance sneakers.

Later that night the boxer-turned-model gushed over his girlfriend who surprised him at the eve of his 25thbirthday by setting up silver balloons with the numbers 25 spelled out in the backseat of their luxury vehicle. In his social media post, he wrote,

“Oh s*** she got me on my way to idknow where 25 yo at midnight.”

Meanwhile, Kourtney also put on quite a show when she spoke before Congress on Capitol Hill on April 24 to lobby for the establishment of Food and Drug Administration laws that would put a stop to the use of substandard make-up that could be harmful to its users.

An advocate for safe, quality make-up since the birth of her first child Mason in 2009, Kourtney told her audience she would appreciate a heads up when it comes to dangerous products so she can keep them away from her family.

“When I had my first son, I started really learning so much about the foods that I was feeding him and it just kind of all snowballed,' she said. 'As a mom, you really take so much interest in the products ... and it's so crazy.”

“It would be nice if we didn't have to guess as much ... if there were regulations to know that the products that we're using are safe.”

Kourtney has three children with ex-husband Scott Dissick. Her eldest, Mason, is now 8 years old while her second child, daughter Penelope is 5. She gave birth to her third child, son Reign in 2014.
