Christina Aguilera and fiancé Matthew Rutler are soaking up the Italian sun — and each other — in Portofino. The longtime couple packed on the PDA during a boat day with friends, with Rutler playfully swinging Aguilera around as they enjoyed they cruised the Mediterranean. Aguilera also gave a nod to her early-2000s style, sporting a blue bandana with her breezy all-white look.
