The 52-year-old former Fly Girl looked flawless in a white Georges Hobeika Couture gown that featured a thigh-high split, ruffled skirt and a string of Swarovski crystal embellished neckline. Her beau looked dapper in a classic tuxedo with black shoes and a chic bow tie.
The duo, who reconnected in April after her split from slugger Alex Rodriguez, stayed close to one another as they held hands and posed for snaps.
