Disick, who is dad to Mason, 4, and Penelope, 2, celebrated his birthday drinking heavily at 1OAK nightclub in the Hamptons before entering Southampton Hospital, where he was treated for alcohol poisoning, the site reports.
A source tells Us Weekly that Disick, who lost both his parents within the past year, "went through a dark place," but, "is doing great now."
The self-proclaimed Lord has been documenting his fun times in the Hamptons as of late, putting his love on full display for Kourtney, who is pregnant with their third child.
On Wednesday, July 16, the 31-year-old posted a vintage-style photo of himself kissing his 35-year-old love in a boat with the caption: "Just Like the Notebook…only better."
Kardashian gave Disick an Instagram shout out as well, posting on July 13 a meme of Dos Equis' Most Interesting Man in The World, which read, "I don't always watch the Kardashians, but when I do, it's for Scott Disick."
