Amelia is in a relationship with Keeping Up With The Kardashians star Scott Disick, 37.

Earlier this month, it was revealed Amelia’s parents were reportedly ‘skeptical’ about her relationship with Scott, considering the pair’s hefty age gap.

It has been claimed that her famous parents struggled with the idea of their daughter dating the father-of-three, before eventually acquiescing.

According to US Weekly, a source said: ‘Her parents were skeptical at first. But seeing their daughter happy makes them feel better about their relationship.’  

Previously, Disick split from Lionel Richie’s daughter Sofia Richie, 22, back in August after dating for three years. They had a 16-year age gap.
