Disick was reportedly celebrating his birthday and took things a little too far. Sources told TMZ that Disick, while slurring his words, insisted he was so drunk he felt someone had drugged him. However, he tested negatively for drugs once at Southampton Hospital.
While Disick was in the hospital, Kardashian was in Los Angeles for her niece North West's first birthday party.
A source told Us Weekly that Disick "went through a dark place" after both his parents died within eight months of one another, but he "is doing great now."
Since then, Disick is reportedly sober and receiving counseling from the pastor who officiated Kim and new husband Kanye West's wedding. He apparently wants to get his act together so he can be a good father.
Disick and Kardashian, who have dated on and off since 2007, have two kids together -- Mason, 4, and Penelope, 2 -- with a third baby on the way.
