Justin Bieber cozies up to model Shanina Shaik

LAS VEGAS, May 4 (UPI) -- Justin Bieber cozied up to Shanina Shaik over the weekend.

The 21-year-old singer and 24-year-old Australian model attended a party at the Rehab pool in Hard Rock Hotel and Casino ahead of the Floyd Mayweather, Jr. vs. Manny Pacquiao fight in Las Vegas.

Bieber and Shaik saw Mayweather defeat Pacquiao in "The Fight of the Century" and subsequently shared a snuggly photo on Instagram. The model captioned the picture, "Thank you Vegas and @justinbieber for a great weekend."

Bieber dismissed romance reports with Shaik last year, writing "Don't even start with the dating rumors" in a selfie caption on Instagram. The pair were spotted getting close at Coachella in April, but the pop star is often linked to his female friends, including Hailey Baldwin and Kendall Jenner.

Bieber dated singer and actress Selena Gomez for several years, while Shaik was last involved with fellow model Tyson Beckford. Shaik came to fame on Australian reality competition Make Me a Supermodel, and is known for her work with Victoria's Secret.
