The group had just had a meal at Italian restaurant called Osteria Mozza. Remove the other friends and that's a hot date!
Fans were quick to jump to the conclusion that we've all been wanting to believe: they're finally dating.
Hailey Bieber even 'liked' the photo... which to us suggests that she wants everyone to know she's supportive of her husband's ex moving on.
“Selena gonna end up marrying Niall,” one fan wrote, as another commented: “Selena doesn’t need a man but Niall would be so good for her. He is the sweetest. They’re on a similar wavelength.”
Another small bit of evidence fans think proves the pair are dating is that Selena gave Niall's new single "Nice To Meet Ya" a special shout out online: “This came out like 5 min ago…and I’m pretty sure you all need to download.”
Supportive GF much?
Selena and Niall were first linked romantically over four years ago, and while neither have ever confirmed a relationship, Selena did tell ET at the time that she’s always had a lot of love and respect for him.
If we've learned anything from Camila Cabello and Shawn Mendes, it's that old friends can turn into lovers very fast.
