Rumors about Justin Bieber and Hailey Baldwin dating have been gracing gossip columns for months now. After speculations and denials, did the "Baby" singer just confirm that he is indeed in a relationship with the model?

Justin Bieber posted a photo of him and Hailey Baldwin cuddling, captioned "The one and only." The two were spotted together in having fun at the beach in Miami, Florida. The 21-year-old singer and the 18-year-old model were seen riding a jet ski together, with Hailey's arms around Justin.

"She held tightly to the pop star during the water ride," Cayla Caldwell wrote on her article in Mail Online. "Only letting go at times to shield her face from splashing water. The two seemed to be in good spirits as they took in the water attraction, and had earlier been seen chatting as they hung out by the pool at Justin's hotel."

However, Justin Bieber and Hailey Baldwin's closeness doesn't seem to be sitting well with some fans. After photos of the two getting cozy circulated online, one fan twitted the model saying, "He's always f--king other girls but if you want to have no self respect do you boo @haileybaldwin." Hailey didn't let the harsh comment go, and needed to express her piece according to E Online. She responded by tweeting, "I have nothing but respect for myself what I chose to do in my personal life is my business!"

One person who doesn't seem to be reacting to Justin Bieber and Hailey Baldwin's Miami trip and their sweet photos is Kendall Jenner, who has been spotted hanging out with the two numerous times these past few months. Did the "Keeping Up With The Kardashians" star feel left out for not being with Justin and Hailey in their beach bumming vacation?

It's not clear whether Kendall was invited to join Justin and Hailey to Miami. However, it seems that the 19-year-old model has a lot in her plate especially now that her camp is purportedly in talks with a production company for the possibility of Kendall starring in a Hollywood movie, according to Mirror.
