Cardi B joined her ex-boyfriend Stefon Diggs at the pre-Mother's Day celebration hosted by his nonprofit less than four months after they broke up. Cardi, 33, and Diggs, 32, were both spotted at the Diggs Deep Foundation Wellness event on Saturday, May 9, according to sports reporter Kelsey Nicole Nelson. In images from the event, the pair were spotted greeting attendees of the "A Moment for Moms" celebration. In another photo shared by Nelson, Diggs wrapped his arms around Cardi's waist as they posed for the camera. The rapper, for her part, used two fingers to point to her giant grin.
