Whether it’s intentional or not, Kourtney Kardashian is certainly showing ex-boyfriend Scott Disick what he’s missing! The 36-year-old and her sisters and Keeping Up With the Kardashians co-stars Kim Kardashian, 34, and Kylie Jenner, 17, took part in a sexy photo shoot on Friday. Kourtney sported a black top that showed some crazy cleavage. “Yeah, photo shoot fresh, lookin like wealth,” Kourtney wrote. “Such a fun shoot today. #sisters,” makeup artist Mary Phillips said on her Instagram page.
