Taylor Swift Introduces Harry Styles To Best Friend Emma Stone As Relationship Progresses

Taylor Swift and Harry Styles must be getting serious. After all, Taylor decided it was time to introduce her not-yet-official boyfriend to on of her best friends, Emma Stone.

On Thursday, the 18-year-old One Direction singer met up with Taylor Swift at a birthday party for one of her friends. There they spent time with Emma Stone, who happens to be a longtime friend of Swift, Us Weekly reported.

Taylor Swift and Emma Stone partied at the McKittrick Hotel, where they saw a production of the interactive theater production of Sleep No More. They then moved on to the Crosby Street Hotel, where they met up with Harry Styles.

At that party, Taylor Swift was reportedly “all over” her boy-band lover, even making out at the table they shared with other party guests, a source told Us Weekly.

The couple has been spending much time together in the past few weeks, including an appearance together at an X Factor performance rehearsal in Los Angeles in November.

Swift and Styles recently spent some extended time in New York City, being spotted together in Central Park and posing for photographs with plans. The two parted ways late in the week as Taylor Swift moved on to Nashville and Harry left for a work engagement.

“They lit up when they saw each other,” a source told Us Weekly.

Introducing Styles to Emma Stone would represent the next step in their relationship.

“My friends are amazing and I’m so thankful to have them, [but] the ones that are like sisters to me are Selena Gomez and Emma Stone,” she revealed to PopSugar last year. “They can predict my thoughts; I’ve known them for so long it’s really cool to have friends that are that close.”
