Is Hailee dating Niall?

It all started with an instagram post. For Hailee Steinfeld's birthday, Niall Horan posted the below photo, calling Hailee, "The loveliest person on the planet and one of my best friends," and ending it with "Love ya Hails." Hailee and Niall were later spotted seeing Hamilton together in London and at Hailee's brother's birthday party. So what's going on? "I am a very private person," Hailee said when asked if the two were more than friends. "I think that sometimes it's hard for people to realize that there are boundaries." Hmm, we can't help but notice she didn't deny the rumor!
