Justin Bieber was the superstar host with the most at the pre-fight Rehab pool party at the Hard Rock Hotel and Casino on Saturday afternoon, ahead of Floyd Mayweather Jr. and Manny Pacquiao’s big fight at the MGM Grand Garden Arena in Las Vegas, Nevada .
The singer walked pal Mayweather out to the ring. But before all that razzmatazz, the star goofed around with his pals as they posed for press shots on the blue carpet at the hotel.
In clearly high spirits, the heartthrob playfully lifted up his white T-shirt before hosting the bash and flexed his abs and pecs.
At the presser, Bieber invited people down to the bash. “Come check out Hard Rock Hotel and Casino,” adding, “Did I say I was Justin Bieber? Because I am.”

Then, it was time to throw down. Shirtlessly, naturally. Amid the fun, the 21-year-old brought to the event, the Canadian performed his infectious Jack U hit “Where Are U Now” live.
At one point during the proceedings, Bieber (or whoever else may access his social media accounts), took to his Fahlo account to write, “We in Vegas getting lit!”
A nearly total eclipse occurred when Bieber hyped up the end of the song by jumping up and down on stage and nearly lost his pants in the process.
Mindful of his hosting duties, hilarity ensued as Bieber got the crowd going when the DJ played Bobby Schmurda’s iconic smash “Hot N****.”
Champagne spraying on the crowd? Yes, that was on the menu too.
There was even a moment where two height-challenged guys fought in a mock-up of the Mayweather Vs. Pacquiao fight .
And there was that time Bieber turned paparazzi on the pool party audience.

The rapper Flo Rida attended the bash, as did gorgeous Australian model Shanina Shaik, who was previously in a long-term relationship with model Tyson Beckford . Back in August, the model was seen hanging out with Bieber on his hired yacht in Ibiza.
At the time, the singer Instagrammed a photo of the pair, tagging Shanina alongside a note telling the world not to “start with dating rumors.”
Obviously, gossip sites did anyway and Beckford famously alluded to Bieber when he told TMZ in a not-at-all manipulated story that, “Little boys can’t have grown man toys that’s all I’m saying,” before charmingly adding, “I ain’t loaning out nothing.”
More recently, Bieber hung out with Shanina at the Coachella Festival last month, along with model pals Kendall Jenner and Hailey Baldwin.
The Biebs originally posted three photos of himself and Shanina on Saturday, before deleting a blurry one which was captioned, “Came with the fits.”
After the party, Bieber walked Mayweather out to the ring, where he beat Pacquiao in 12 rounds by unanimous decision, bringing his undefeated record to 48-0.
Earlier Saturday, Bieber tweeted Mayweather, writing , “2 great fighters tonight. Gonna be a great night. Let’s go Champ!”

Mayweather will fight his last fight in the fall. After praising Manny as a “tough competitor” and a “true champion,” he told press, “My last fight is in September. I’ll do that and I will hang it up.”
Meanwhile, Manny said, “I thought I won the fight. He didn’t do anything. He always ran.”
