Justin Bieber has fueled reports he is dating model Hailey Baldwin by posting a photograph on social media featuring him locking lips with his longtime friend.

The Sorry singer, 21, and actor Stephen Baldwin's daughter, 19, are currently vacationing together in Anguilla and during their stay in the tropical paradise, rumors began circulating suggesting they are an item.

On Sunday (03Jan16), Justin seemingly confirmed their relationship by taking to Instagram.com with a captionless picture which features him passionately kissing Hailey. He posted another photo of them snuggling next to each other on a couch, but again, did not add context for the image.

Justin and Hailey, who have been good friends for years, have had to brush off gossip of their rumored romance in the past, with the fashion star telling Billboard magazine in November (15) that the singer is "one of my best friends in the entire world".

Justin has already had an eventful 2016, ringing in the New Year at Leonardo DiCaprio's private party on the Caribbean island, where Robin Thicke and his girlfriend April Love Geary, actors Kevin Connolly and Lukas Haas, and the Duchess of Cambridge's younger brother James Middleton were among the guests.
