Serena Williams and her mini-me daughter Olympia Ohanian, have celebrated Mother’s Day with a gelato date in Rome! The pair were joined by her husband Alexis Ohanian, with whom the tennis champ shares her three-year-old daughter. As they strolled the streets of Italy, Serena and Olympia looked like twins in pink sneakers, as they walked hand-in-hand while eating their waffle cones. The mom-of-one rocked a pale green Nike sweater, matching shorts, and a Gucci crossbody bag.
