Makin' time for mom! Sofia Richie bonded with mom Diane Alexander over brunch, on Thursday, the 21-year-old taking a break from boyfriend Scott Disick to spend time with mom.

Sofia dressed down for the outing -- looking cute and casual in a Chanel baseball cap, mom jeans, and gladiator sandals. It was Sof's mom Diane who stunned -- she's 52, super-fit, a former dancer and RICH. Diane was awarded an estimated settlement of $20 MILLION in her divorce from Sofia's dad Lionel Richie!!! Among her alimony demands: a $15,000 monthly clothing allowance; $50,000 a month for manicures, massages, vitamins, and other personal services; and a plastic surgery budget of $20,000 a year. That makes sense, right?!
