On Wednesday, the couple stepped out for dinner at Giorgio Baldi in Santa Monica, California.
Swift, 26, and Harris, 32, left the Italian eatery hand-in-hand, as she glanced up at him with an adoring smile.
Continuing the new era in her fashion evolution, the “Style” singer donned a black mini-dress with black heels, a black clutch purse and her signature red lipstick.
Meanwhile, the Scottish deejay/producer opted for a casual look, donning a button-down shirt with jeans and sneakers.
Swift and Harris are big fans of the restaurant, where a young fan crashed one of their date nights in January.
“They are the cutest couple,” a Giorgio Baldi source recently told PEOPLE.
The romantic outing comes just days after Swift gave Harris an extra special shoutout at the 2016 iHeartRadio Music Awards in Los Angeles, where she took home four awards, including best tour.
“For the first time I had the most amazing person to come home to when the crowds were all gone and the spotlight went out, so I’d like to thank my boyfriend Adam for that,” she said, calling Harris by his real name, Adam Richard Wiles.

Last month, the couple celebrated their one-year anniversary during a tropical getaway.
“Of course they love each other, but they are not the type of people to rush down the altar,” the source said. “They are both very solid people.”
