Scott and Kourtney, who share three children -- 6-year-old son Mason, 3-year-old daughter Penelope and 10-month-old son Reign -- called it quits in July when Scott was photographed getting close with his ex-girlfriend Chloe Bartoli.
Since then, Scott has been coping with the split by making guest appearances at Las Vegas night clubs and getting cozy with 18-year-old Canadian model Lindsay Vrckovnik. The two were even seen spending time on the beach in Miami earlier this month.
But at least we know Scott is staying strong, and despite his many hardships and obstacles, he's never going to give up.
Although he did seem pretty broken up in a recent sneak peek at the season 11 premiere of Keeping Up With the Kardashians. Check out the video below to hear Scott tell his ex, "I made the worst decision I've ever made in my life."
