Sofia Richie appears to be the latest love interest of Justin Bieber.

Another day, another leading lady, and today, it is Richie, 17, who is being linked to the 22-year-old singer, who was caught naked with rumored fling Sahara Ray just days ago,

This week, Bieber has been spotted with Richie a number of times and many are wondering how her famous family feels about her spending time with the playboy.

“Nicole is not worried about Sofia & Justin, she has her own kids to worry about. There is a huge age gap between Sofia and Nicole, so they never had that tell each other everything kind of relationship,” a source revealed to Hollywood Life on Thursday. “Nicole is that last one to judge anyone’s relationship. She feels that if Justin and Sofia are having fun, then good for them. She is not worried about Sofia & Justin at all. She has her own kids and family and more important things to think about.”

As for how Richie has been handing the relationship, a second source claimed that hanging out with an older crowd is nothing new for Richie.

“Sofia runs with a much older crowd, most of her close friends are in their 20’s and some are even in their 30’s so the age difference between her and Justin really isn’t a big deal in her world,” a source explained to Hollywood Life on Wednesday.
