Fractured Family? Sofia Richie Not Photographed With Dad Or Sister In Over 1 Year

It appears that Sofia Richie is keeping up with the Kardashians more than she's hanging out with her own famous family!

RadarOnline.com has learned the last time Sofia, 20, was seen in public with her father, Lionel, 70, and fashion designer sister Nicole, 37, was on March 7, 2018 at the iconic singer's Hand and Footprint Ceremony in Hollywood — meaning it's been over a year since the formerly tight-knit family stepped out together in the spotlight.

And according to a Richie family insider, Sofia "only has herself to blame!"

The insider insisted her romance with much-older bad boy Scott Disick, 36, put a rift between the celebrity family members.

"There are just a lot of hurt feelings, because Lionel was really hoping Scott was just a phase in Sofia's young life," the insider added of the couple, who have been dating for two years.

But a separate source told RadarOnline.com Lionel is concerned his daughter is also struggling with relationship doubts.

"He sees her hurting too because of Scott's relationship with Kourtney Kardashian, and he knows Sofia is very invested in it. Lionel also knows what it's like to put his kids first," the second source told RadarOnline.com.

"She has been credited with practically saving Scott's life after he suffered a mental breakdown following his breakup with Kourtney," the source said, adding that Scott has been on his "best behavior" lately.

Despite her father and sister's disapproval, Sofia isn't likely to go anywhere anytime soon.

Scott and Kourtney's kids — Mason, 9, Penelope, 7, and Reign, 4 — are all "very fond of Sofia and love her like a second mom," the source insisted.

In April, sources close to the pair claimed Sofia is "begging" for Scott to put a ring on it.
