Floyd Mayweather and Justin Bieber are an unlikely pair, but they're the best of friends. Mayweather and Bieber's "bromance" doesn't stop as soon as the undefeated boxer steps out of the ring. The Canadian pop star also supports Mayweather on the business side of things beyond the ring.

According to Fighthype.com, Mayweather and Bieber have so many things in common. Not known to many, Mayweather and Bieber met through John Shahidi, the co-founder and chief executive officer of Shots Mobile, Inc. Shahidi's company later on developed an anti-bullying application called Shots where in users can post pictures that neither can be filtered nor edited, without a commenting platform.

The pair are among the celebrities who take bullying seriously. It is the very reason why they were so keen to support the Shots app. "It is the one place where they can feel comfortable freely sharing positive moments of their lives without the worry of negativity and ridicule from naysayers."

The Web site further reported that Mayweather and Bieber have plans of putting up more businesses in the future.

"It was clear that this seemingly odd couple have a strong, honest friendship much deeper than what many assume."

Ever since Mayweather and Bieber became friends, the "Baby" singer has always been a regular member of Mayweather's entourage. Bieber, along with Lil' Wayne escorted Mayweather to the boxing ring at the MGM Grand Arena in Las Vegas on May 3 during his fight against Marcos Maidana.
