How imminent is a Sofia Richie-Scott Disick engagement? Not very, Us Weekly reports today. While a source told the outlet that the 20-year-old model and 35-year-old reality star are 'extremely serious' after roughly two years of dating, that same source cautioned that a baby would come before any engagement ring. 'It’s more likely that she gets pregnant before they get engaged,' the source said.

A second source reassured Us that the two don't have immediate plans to start a family together. Their focus is on Scott's family with his ex, Kourtney Kardashian. Kardashian and Scott share three young children: Reign, Penelope, and Mason. 'Sofia spends time with Scott’s kids and she even has a relationship with his ex, Kourtney Kardashian,' a source told the outlet.

People reported back in December that Richie understands that she and Kardashian aren't destined to be super close, although she's glad the two have some kind of relationship. 'She knows that Kourtney isn’t her biggest fan and she understands that,' a source told the outlet then. 'Sofia and Kourtney will never be best friends, but Sofia is happy that she has proved to Kourtney that she is great with her kids.'

Should Disick feel compelled to pop the question to Richie though, Kardashian would not be bothered. Kardashian appeared on Watch What Happens Live last week with her sisters, where she told Andy Cohen that she would just say 'Congratulations' to them if they got engaged. Her sisters Kim and Khloe additionally pointed out that they've all vacationed together so Richie is essentially part of the family. No drama there.
