Scott Disick isn’t taking Kourtney Kardashian and Travis Barker’s engagement news well.
A source exclusively told Page Six that the Talentless founder is losing his mind over the impending nuptials — which is why fans knew to check in on him after the news broke late Sunday.
"Scott is going crazy," our insider said. "He’s going to go off the deep end. It’s really bad. It’s about to get dark."
A rep for Disick didn’t immediately return Page Six’s request for comment.
KOURTNEY KARDASHIAN AND TRAVIS BARKER ENGAGED
Barker proposed to Kardashian on the beach in Montecito, Calif., with an oval-cut diamond ring estimated to be worth $1 million.
Disick shares three children with his ex: 11-year-old son Mason, 9-year-old daughter Penelope and 6-year-old son Reign.
While the former "Flip It Like Disick" star, 38, may not be thrilled about the engagement, he gave his blessing to Kardashian’s relationship with the Blink-182 drummer during the "Keeping Up With the Kardashians" reunion, which aired in June.
"I mean, yeah," Disick told host Andy Cohen when asked point-blank whether he’d "bless" the couple’s romance. "I think if you really love somebody right, you want them to be happy no matter what. So, I do give her a blessing to be happy."
In hindsight, it doesn’t look like Disick meant what he said because he later shaded the Poosh founder’s PDA with Barker in an Instagram DM to one of her other exes, Younes Bendjima.
"Yo is this chick ok!???? Broooo like what is this. In the middle of Italy," Disick appeared to write to Bendjima, attaching a photo of Kardashian, 42, mounting Barker, 45, on a boat.
"Doesn’t matter to me as long as she’s happy," Bendjima, who screenshotted the messages and then shared them, purportedly responded. "PS: i aint your bro."
Disick and then-girlfriend Amelia Gray Hamlin broke up shortly thereafter.
