According to Us Magazine reports, Kourtney, 35, has become paranoid since her 31-year-old partner goes out more and supposedly often stays at the Montage Beverly Hills Hotel.
As shown on episodes of reality TV show Keeping Up With The Kardashians, Kourtney has been suspicious of Scott when she has found text messages on his phone in the past.
Despite a source claim that Scott has been sleeping at various hotels, the mum-of-three refuses to believe anything without any evidence – “not without pictures of him with another woman.”
Speculations have arisen amongst the show’s fans stating whether Scott is staying with Kourtney because of their children; Mason, five, Penelope, two and newborn son, Reign.
A source told the magazine: “She has nothing in writing in terms of parental custody — they have never even discussed what would happen if they broke up.
“She hasn’t even though about splitting the house and their time with the kids. Kourtney doesn’t think like a partner, she thinks like a mom and Mason never wants to leave Scott’s side.
“Even though he’s a negligent boyfriend, Scott is a good dad.”
