Sofia Richie, 21, proved she’s staying active despite reports that her ex Scott Disick, 37, stopped their on-again, off-again relationship when she was seen playing tennis on Aug. 19. The blonde beauty wore a white tank top, black Nike skirt, white socks and white sneakers during the Los Angeles outing and gave off serious expressions as she swung the racket in the hot weather. She had her long locks up in a ponytail and flashed a smile more than once during the match.
