Taylor Swift and Harry Styles PDA: Couple kiss constantly at New York birthday bash

Another day, another date for newly glued-at-the-hip couple, Taylor Swift and Harry Styles. The lovebirds were spotted at a star-studded birthday bash in New York, and this time they did a lot more than hold hands in public.

A witness reports Harry and Taylor were openly making out, telling People the couple was "being very smoochie." The party spy adds, "They're not trying to hide it. The bar was packed."

Harry and Taylor joined guests Emma Stone and "Glee's" Dianna Agron in singing "Happy Birthday" to the lucky party host. Harry was reportedly acting quite protective over his new love, keeping his arm wrapped around her,

The newly crowned "Haylor" eventually departed the bar holding hands, no doubt headed for one of their seemingly regular hotel sleepovers.
