Taylor Swift Shows Some Serious Leg on Sleepover Date With Calvin Harris

Taylor Swift and Calvin Harris are still going strong!

The statuesque couple enjoyed a date night on Tuesday in New York City, going for pizza at L'asso restaurant in Little Italy. The 25-year-old "Bad Blood" singer showed off her slim stomach in a baby blue matching crop top and skirt ensemble by Aqua, and put her long legs on display in sky-high nude stilettos.

For his part, Calvin kept it cool in jeans and a black leather jacket, sporting Adidas sneakers.

Clearly, the pair is still in the honeymoon phase of their relationship. "They were laughing and talking and Calvin was kissing her hand," an eyewitness tells ET about their hour-and-a-half pizza date. The 31-year-old DJ/producer was also spotted going back to Taylor's pad with his luggage, presumably staying at her place for the night.
