The Candy starlet paired her look with several layers of chunky gold jewelry, also hiding her face from the sun with a chic pair of black sunglasses.
She kept her chestnut brown locks tied loosely in a sleek ponytail to keep her hair out of her face for the day’s itinerary.
The couple enjoyed an action-packed day, exploring the famous Catacombs of San Callisto and splurging at the world-famous Borsalino hat store.
Earlier this weekend, the pair put on a loved-up display visiting the famous Trevi Fountain.
The NSYNC founding member was seen even throwing a coin into the fountain to make a wish, a tradition at the Trevi.
While the couple have been married now for eleven years and counting, the Grammy Award winner jokingly re-proposed to his wife in the comments of an Instagram post of hers where she referred to him as ‘my boyfriend.’
Proving that he had a sense of humor about his spouse’s playful roast, the Tennessean-born singer wrote in the comments section, ‘I know this sounds crazy, but will you marry me?’ with a heart eyes emoji.
Italy was actually the site of the pair’s nuptials back in 2012, where they pledged their love for each other in a private ceremony at the Borgo Egnazia resort.
Telling People that she had, ‘a little bit of butterflies,’ regarding her wedding, the brunette beauty added, ‘I was about to stand up in front of my friends and family and bare my soul for the person I love. It was terribly emotional.’
