Scott, who dated Kourtney Kardashian on-and-off for about ten years and is father of their three children: Mason, Penelope and Reign, was spotted with Amelia by TMZ looking very cozy at the beach together.
The Keeping Up With The Kardashians star began his last relationship with Sofia Richie when she was also 19-years-old.
Amelia's parents, Real Housewives of Beverly Hills stars Lisa Rinna and Harry Hamlin, apparently believe this new relationship is "just a phase" and had been upset to see her split with former boyfriend, Mercer Wiederhorn.
"Harry and Lisa were sad to see Amelia and Mercer Wiederhorn split because they loved Mercer," a source shared with E! News. "He was like family, but they understand."
While it's early days for Scott and Amelia, an insider has claimed things between them aren’t that serious.
"Scott's having a good time," the source told the publication. "He's getting to know Amelia and enjoying her company. They are spending a lot of time together but it's nothing serious. He's having fun with it."
The relationship has sparked a lot of conversation on social media, with one user even pointing out the fact Amelia is closer in age to Scott's 10-year-old son Mason than she is to him.
"Amelia Hamlin is closer in age to Mason than Scott Disick and that should be concerning," the Twitter user wrote.
"If we’re gonna be outraged by Charles (31) and Diana (18) can we also please be outraged by Scott Disick (37) and Amelia Hamlin (19) as well?" writer Sophie Ross tweeted, referencing the relationship between Prince Charles and Princess Diana currently playing out on the new season of The Crown.
"Reading about 37 year old Scott Disick dating a 19 year old Amelia Hamlin made me barf on my keyboard," another Twitter user wrote. "He was already out of high school before she was born. Makes me Di-sick."
