Zöe Kravitz and Harry Styles turned up the heat on their apparent romance with a butt-grabbing outing.

In photos, the “Watermelon Sugar” hitmaker stepped out with the “Blink Twice” actress in Rome on Friday while holding hands and chatting. In one photo, the singer grabbed Kravitz’s rear, and in another snap, she casually returned the favor during their affectionate walk.

For the sunny outing, Kravitz, 36, wore a black, lace-lined slip dress with red ballerina flats. She accessorized with sunglasses and carried a straw handbag, and styled her voluminous waves around her shoulders.

Styles, 31, rocked jeans and a white T-shirt with sneakers, slinging a denim jacket over his shoulder and donning a pair of sunglasses.
