Kourtney Kardashian stepped out on Friday for the first time since her longtime boyfriend, Scott Disick, was photographed hanging out with another woman in Monaco.

The mom of three wore skin-tight skinny jeans, towering stilettos and a white long-sleeve crop top that showed off her toned tummy as she was spotted out in Van Nuys, California.

While Kardashian remained at home to look after the couple’s kids – Mason, 5, Penelope, 2, and Reign, 6 months – Disick was 6,000 miles away, soaking up the sun on the Mediterranean.

Can Kourtney Trust Scott?

On Thursday he was photographed cozying up by the pool in Monte Carlo with his friend Chloe Bartoli, rubbing her back, and even appeared to be holding hands with the 25-year-old at one point.

The pair reportedly dated shortly before Disick, 32, and Kardashian got serious.
