The 36-year-old reality TV star, who recently ended her relationship with her hard-partying boyfriend of nine years after images surfaced of his canoodling with ex-girlfriend Chloe Bartoli in the South of France, has reportedly warned him that he can't spend time with their sons, Mason, five, and Reign, six months, or three-year-old daughter Penelope until he gets sober.

A source close to the 'Keeping Up with the Kardashians' star said: "It's not even the girls that bother Kourtney right now -- it's the drinking and drugs. She's genuinely worried that he's going to die. She's actually trying to be civil with him, but she doesn't even want him around the children."

The 32-year-old entrepreneur has spent several short stints in rehab over the past year, but his friends are also very concerned by his recent destructive behaviour.

The insider told the New York Daily News: "Even Scott's friends who usually say, 'Oh, this is Scott being Scott,' think this is the worst he's ever been. He's showing up to business meetings wasted. Even they don't think he should be around the kids."

The one-time restauranteur briefly checked into rehab in Florida earlier this week, but left within 24 hours and his friends are now said to be planning to stage an intervention.
