Scott Disick really messed up this time.
In this exclusive clip from tonight's season finale of Keeping Up With the Kardashians, Kim Kardashian and Kris Jenner discover photos of Scott getting handy with a lady who isn't his girlfriend and baby mama, Kourtney Kardashian.
They first learn of the betrayal from cousin Cici Bussey who calls Kim to tell her she saw pictures of Scott on the Internet with another woman. "Scott, front and center, Daily Mail, arms around a girl, laying down together with their arms around each other," she describes.
"No!" Kris exclaims. "That piece of s--t!"
Kris immediately goes online to find the shocking story for herself. "It's just embarrassing," Kim says.
