You may be rooting for Justin Bieber and Selena Gomez, or Justin Bieber and Kourtney Kardashian, or Justin Bieber and you, but it looks like it鈥檚 Hailey Baldwin that鈥檚 keeping the Biebs company this week. The pair celebrated New Year鈥檚 on the beach in both Anguilla and St. Barts, and it鈥檚 been more than the sun that鈥檚 making things hot, Hot, HOT! In fact, it might be the super-sizzling pair plus a little science and chemistry in the mix that鈥檚 making things go positively supernova. No, really: It鈥檚 not just margaritas 鈥 there鈥檚 science at play here.

Justin confirmed the rumors of the duo鈥檚 relationship by posting pics on his Instagram account that show the cutie couple embracing with a kiss as well as a pic where Justin is clearly admiring Hailey鈥檚, uh, dress. (Yup, he鈥檚 totally looking at her鈥 dress.)

But if you were thinking this is just a fling for the pair, you might need to reconsider. The young duo have been friends for years, and according to a recent study from Psychological Science, that can be the key to a lasting love. As the Daily Beastreported last June: 鈥淢ore than showing that plenty of relationships start as friendships鈥 research shows that the longer you鈥檙e friends with someone, the more possible ways there are for that person to be attracted to you 鈥 instead of matching how other people see you, your friends are able to have more idiosyncratic and deeper feelings.鈥 Hmm, might make you look at your own long-time flirty friends a little differently.

Do you think Justin Bieber and Hailey Baldwin make a good pair? Let us know @britandco.
