The Flip It Like Disick alum is "getting back out on the dating scene and enjoying himself," an E! News insider revealed.
The reality star is not said to be looking for anything serious. "He's having fun with Hana but that's all it is for now," the source noted.
"Meeting new girls and going out is a nice distraction and is helping him move on," the source explained. "He's trying to have fun and keep it light."
An insider previously told PEOPLE that Disick was "shocked" about the break-up. "He has slowly been dating, but is not serious with anyone," the source continued. "He seems good though. He is around for his kids a lot. He loves spending time with them."
The Blink-182 drummer popped the question to the Poosh founder in October. Disick and Hamlin reportedly split in September.
As previously reported by OK!, the 20-year-old model reportedly broke up with the reality star after he was embroiled in a DM scandal with Kardashian's ex Younes Bendjima. Disick allegedly messaged the model and slammed Kardashian and Barker's PDA-heavy romance.
