One Step at a Time! Kourtney Kardashian Breaks Social Media Silence After Split from Scott Disick

A little rain and a messy breakup certainly don't seem to be getting Kourtney Kardashian down. 

The Keeping Up with the Kardashians star made her first appearance on social media since splitting with Scott Disick in the midst of cheating allegations against her longtime boyfriend and the father of her three children. 

On Thursday afternoon, Kardashian posted an Instagram shot of herself getting physical in a drizzly "workout sesh" with sisters Khloé, 31, and Kim, 34.
