Kourtney Kardashian is showing off her post-breakup body with her most risqué outfits since splitting with longtime love Scott Disick. The mother of three spent sister Kylie Jenner’s birthday weekend celebrating with the family and flaunting her banging figure.

On Friday, E! Online shared a photo of Kourtney as she warmed things up by wearing a body-hugging outfit that didn’t reveal too much skin. She went to Kylie’s birthday dinner at Nobu Malibu wearing a 1970s-inspired pair of flare pants. She brought in the sexy factor with a body-hugging top and a low neckline.

The following day, Kardashian and sister Kim showed off a lot of cleavage when they posed for a photo with matching low-cut black outfits. Kourtney shared the pic on Instagram, where they also sported matching hairstyles with wavy hair and short bangs. Kourtney wore a black studded corset, while Kim wore a plunging V-neck latex dress.

On Sunday, day three of Kylie’s birthday celebration, Kourtney really showed Disick what he’s been missing. She showed up for dinner with her family and friends at the Nice Guy in Los Angeles, wearing a tight black catsuit with large cut-out panels on both sides of her torso. Needless to say, the outfit showed off her tight abs and petite frame.

Kardashian also posted photos of herself on Instagram from that evening. In some photos, she could be seen goofing off with her supermodel sister Kendall Jenner while inside the restaurant’s kitchen. Despite having three kids, one of them only eight months old, Kardashian can still give her supermodel sister a run for her money. Kendall wore a white crop top and a skirt with a hip-high slit alongside her older sister.

While Kardashian is out flaunting her post-breakup bod, her ex, Disick, was busy spending some quality time with their children. He was spotted taking Mason, 5 and Penelope, 3, out to dinner on Friday. The couple also have an 8-month-old son, Reign. Kardashian and Disick were together for nearly 10 years before calling it quits in early July.
