Amelia Hamlin has officially split from Scott Disick, and a source close to the model has revealed she’s unfazed by her ex dating again. “Amelia has totally moved on since her relationship with Scott,” an insider close to the 20-year-old told HollywoodLife exclusively. “She’s happy doing her own thing, working on her career, and is excited about her future in general. She really isn’t holding onto any type of hope of a reconciliation between her and Scott.”
