Justin Bieber and Hailey Baldwin Pack on PDA During New Years' Vacation

There's no word on if they're a couple, but the two surely are getting close.

The model captioned the photo: "New Years."

Baldwin, 19, and Bieber have side-stepped romance rumors for a while. Although Beliebers have already created a moniker for the two -- "Jailey" -- Baldwin told E! News last month that she was just friends with the pop star.

"I've known him since I was so young -- since I was like 13 -- and we've just been good friends over the years," she said. "We have just stayed close and there's nothing more to it than that."

Based on other photos posted to Instagram earlier this week by Baldwin and Beiber, it seems the two have spent a couple of days together with Bieber's family, including his father, Jeremy.
