Cheban, 41, who is the founder of celebrity lifestyle site TheDishh.Com, said the couple will get back to normal once Disick is back from his voluntary rehab visit, reported People magazine.
"I'm sure they can work it out. There's three kids, he lives not that far from her. Once he gets this out of his system I'm hoping that it will be somewhat back to normal," he said.
Calling Kourtney "forgiving", Cheban says he does not give any advice to her 32-year-old partner as he may act rebellious.
