A few years ago, Sofia Richie would have been spotted at Coachella with her former beau Justin Bieber but this year, she is back to step-mom duties as she tries her hand at co-parenting with Scott Disick. As Kourtney Kardashian enjoys the Indio festival with sister Kylie and boyfriend Younes Bendjima, Scott Disick was in charge of taking care of the former couple's children. With Sofia Richie in tow, the pair schlepped around Mason, Penelope, and Reign as they hit up a toy store in Malibu.

Scott and Sofia started hanging out last year and the couple is still going strong, much to the surprise of pretty much everybody. Lionel Richie claimed earlier this year that his daughter's relationship with Kardashian-linked Scott was "just a phase" but the phase has lasted a while at this point. With Sofia now being spotted caring for the kids on more than one occasion, the two are seriously getting closer as she gets more involved with the family. Perhaps Scott and Kourtney are splitting weekends as Coachella continues for its second week on April 20.

TMZ reported that Scott's daddy duties were not assumed alone as they photographed the couple with all three of Kourtney and his children in Malibu. The photos of Sofia & Scott can be viewed here while Kourtney parties it up below.
