Justin was in Vegas last night, along with 50 Cent and Lil Wayne, to root for Floyd in his fight against Miguel Cotto for the junior middleweight title. And it looks like Justin might be a lucky charm, because Floyd won!
Before the match, the Biebs and the boxer known as "Money" Tweeted each other.
"cinco de mayo.... #MayweatherCotto yeah @FloydMayweather today is a BIG day," Justin Tweeted.
Floyd responded: "justin bieber keep up the great work and thanks for the support #TheMoneyTeam. Enjoy the fight."
We're sure he did! After the fight, Justin Tweeted his support once more, saying: "@FloydMayweather Hard Work & Dedication. congrats champ. glad i could be part of it."
We already knew Justin felt a bond with Floyd; in the February V Magazine, he compared himself to the boxer, noting that now that he's on top, people want to bring him down."
Well, we don't know who wants to bring down the Biebs, but it's definitely not us!
