She doesn't give AF.
A source tells E! News Kourtney doesn't care what Scott does because they're not together. In fact, while they've been on better terms lately—vacationing together with the Kardashians in Costa Rica over the past week—we're told they haven't been romantically connected in a very long time.
"They were never 'back on,'" the insider explained. "They don't even live together."

With that being said, Scott was openly cuddling up to a brunette woman in Miami on Monday, just a few days after leaving Costa Rica.
In photos released by the DailyMail, the woman—who we've learned is model Jessica Harris aka J. Lynne—wraps her legs around him, wearing a thong bathing suit while flirting in the pool. In some of the pictures, Scott is seen kissing her neck and holding her close, smoking cigarettes and splashing around.
Harris is a Philadelphia native who recently moved to Miami where she works as a model. TMZ is reporting the two casually met and hung out at the pool just for the day.
She took to Twitter after her photos with Scott surfaced, writing, "Miami is always a movie," later adding, "I prefer being lowkey."
She also tweeted, "#mindyabusiness #baltimoreclubvoice."
Kourtney, on the other hand, has been brushing off the news and having some fun in the sun herself.
Meanwhile, the former couple have been spending more time together recently. Other than jetting off to South America, they spent the holidays together, too.
Still, they've always remained amicable, even after Kourtney first split from her boyfriend of nine years in July of 2015.
