Her father Stephen Baldwin already let the cat out of the bag in a tweet on Saturday. But yesterday, Justin Bieber himself confirmed he and Hailey Baldwin are engaged, in a tasteful black and white Instagram post of the loved-up couple. “My heart is COMPLETELY and FULLY YOURS,” said Bieber in the romantic social media gesture that confirmed that the pair have been engaged since Saturday. In the snap, Baldwin sat in the lap of her new fiance and kissed his cheek. On her ring finger was a band inlaid with diamonds - but it is worth noting this was a different piece of jewelry to the ring Hailey was pictured wearing in the Bahamas over the weekend.
