This couple is definitely in style sync.

Christina Aguilera and her fiancé Matthew Rutler stepped out for the 5th annual Baby2Baby Gala over the weekend, and they coordinated in matching black ensembles. For the occasion, the singer opted for a plunging black long-sleeve jumpsuit that she paired with towering bejeweled heels, a studded leather bag, and an assortment of dazzling jewelry, while her beau looked dapper in a tailored black suit, white collared shirt, cool plaid tie, and casual black sneakers.

Inside the event, the pair got cozy and kept close throughout the evening and posed for several sweet photos together.

We definitely wouldn't mind seeing more of these two.
