Strong bond! Kylie Jenner and Sofia Richie are “like sisters” these days, a source exclusively dished to Life & Style. It’s no secret that the Keeping Up With the Kardashians star and girlfriend of Scott Disick have been getting extremely close over the past year, and it turns out, they have a lot in common besides their social circles. The billionaire mogul keeps a very small group of trustworthy friends around her, and the model has proven to be a reliable pal.

“Kylie’s sisters tend to ‘yes’ her so she started going to Sofia for advice and very quickly Kylie was really surprised by how much they had in common,” the insider dished. “Don’t forget that Sofia grew up in a famous household, too. And, she has a famous sister, too, and she understands — even if it’s on a smaller level — everything that Kylie is going through. Now they’re like sisters — they share clothes and style tips and just genuinely like hanging out with each other.”

Part of Kylie, 22, and the 21-year-old’s immediate friendship could be that they’re close in age. They also grew up in a similar (and unconventional) way considering the bikini model’s father is Lionel Richie and her adopted sister, Nicole Richie, rocketed to fame while on The Simple Life during the early 2000s.

“Kylie and Sofia really first bonded over the fact that Kylie doesn’t have many people to confide in. Besides her sisters, that is,” a source continued about the reality clan. “Sofia was always around the family and Kylie always knew she was very trustworthy because she’d never betray Scott — even if they broke up — and spill Kardashian secrets.”

Sofia started dating Scott, 36, about two years ago. Although she initially kept her romance separate from the famous family, she has become close with all of them. She and the mother of Scott’s three kids, Kourtney Kardashian, have vacationed together. Sofia has given shout outs to Kim Kardashian‘s brands like KKW Beauty and SKIMS. However, she and Kylie definitely share a special bond and are always spotted hanging out.

We are definitely here for Sofia and Kylie’s sweet friendship. Keep slaying, ladies!
