The model recently raised eyebrows when she was spotted with bruised lips — which often occurs after lip filler injections — and "Harry and Lisa drew a line in the sand," spills the source. "They're concerned that Scott's convincing her to mess with her appearance, especially since she's talking about boob and butt surgery to keep his eyes off other girls."
Ever since the May-December couple hooked up last October, "Harry and Lisa have been sitting back and hoping that Amelia would come to her senses. But it's clear she's in way too deep now, and that they need to make their feelings known," the source adds. "The worry is that Amelia will be pregnant before she knows it, so Harry and Lisa are ready to take the bull by the horns before Scott ruins their daughter's life!"
"Amelia's young and in love, but her parents are hoping they can get through to her," says the source. "They don't want her world to revolve around Scott."
Thus far, Rinna has remained pretty tight-lipped when it comes to her daughter's relationship. After months of staying silent about the couple's romance since it began in October, she finally acknowledged the elephant in the room by posting a photo of Disick and her daughter to her social media last month.
“Welp we both seem to share a love of bucket hats,” Rinna teased, referring to the KUWTK star's accessory.
It's quite likely that Amelia's parents are not huge fans of the self-proclaimed Lord, who is 18 years her senior, as OK! previously reported that the family was missing the model’s ex, Mercer Wiederhorn.
"Harry and Lisa were sad to see Amelia and Mercer Wiederhorn split because they loved Mercer," a source told E!. "He was like family, but they understand."
