A source told Hollywood Life that Richie's new look has even started to bother Kardashian and creep her out.
"Kourtney is definitely more than a little creeped out by how Sofia appears to be stealing her look," the source stated.
The source further explained that Kardashian thinks Disick is behind Richie's new look and is probably manipulating her to the very least.
As Richie's Instagram followers know she was originally sporting blonde locks prior to dating Disick and even kept them for a while throughout their relationship. However, in December 2017, the 19-year-old model took to Instagram to debut her new brunette tresses.
Sofia And Scott
As previously reported, Disick and Richie were romantically linked when they were spotted together at the Cannes Film Festival in May 2017, but neither of the two confirmed nor denied their relationship.
Months later, in December 2017, the duo made their first public appearance while in Miami at Art Basel and ever since the couple has not been shy about their love for each other.
On Thursday, March 15 the pair was spotted out after the model attended her dad, Lionel Richie's imprinting ceremony in Hollywood, California.
Disick and Richie were caught leaving Barneys New York in Beverly Hills.
For the errand, Richie wore her hair in a bun with a black button up top and cut-off jean shorts with black sunglasses and black booties, while the father of three wore a beige sweatshirt with jeans and white sneakers.
Though the two have been together for some time now, Richie was reportedly mistaken for Kourtney Kardashian as she allegedly "stole" one of the reality star's ensembles.
Then on Saturday, March 17 paparazzi spotted the lovebirds as they stepped out together in Malibu, California to enjoy a sweet treat.
For the outing, Disick wore a light blue hoodie with black sneakers and a dark blue beanie, while Richie opted for a gray turtleneck sweater, jeans, and black stiletto boots.
Kourtney Moves On
Although Disick and Richie have been together for almost a year now, Kardashian has also moved on to a new relationship. The 38-year-old has been with her 24-year-old beau, Younes Bendjima ever since they met at Paris Fashion Week in 2016.
Their relationship has gotten so serious that Bendjima has even met Kardashian's three kids that she shares with Disick -- Mason, Penelope, and Reign.
