Justin Bieber may have been in Las Vegas to show support for his buddy, Floyd Mayweather, before the fight. But it looks like he was also getting cozy with Victoria Secret model Shanina Shaik.

The "Boyfriend" pop star posted a photo of the two posing real close together on the red carpet before the big Mayweather and Pacquiao fight on Saturday evening (May 2) at the MGM Grand. But this wasn't all, the two were posing for cameras again at the Rehab Pool Party in the Hard Rock hotel earlier that day. Shanina, who was in a black swimsuit and oversized stripped button down shirt, stayed by his side at VIP.

Rumors about the two have been circulating since Justin posted a selfie of him and Shanina hanging out in Ibiza last year. While he immediately squashed rumors of the two getting romantic, the new black and white pic of them really makes you think differently.

Justin has been linked to other ladies in the past after his relationship with Selena Gomez -- namely Kendall Jenner. After the two were spotted hanging out at Coachella, buzz sparked questioning whether or not they were just friends. So we'll just have to wait and see who Justin really ends up with in the end.

In the meantime, Justin has also been trying to move on from his bad boy image and focus on better things. Despite some of the legal issues he's been going through recently, he has plans to change things in his life and be more of a role model for his younger siblings.

"I love my brother and sister so much," he told People. "I want to help them be the best they can be and being someone they can look up to is definitely an important part of that."

Justin might still be having fun at parties, but he's working on slowing that down more and being around good people -- besides he's got a new album to work on so he needs to focus.

"There have been times where it has been difficult," he said. "But as long as I put God and family first, I can find my way through most things. I also find it important to surround myself with people who are honest and hold me accountable for my actions – that helps a lot, too."
