After the release of his music video for “Boyfriend,” Justin Bieber took some time to enjoy his success in Las Vegas, NV on Saturday night (May 5).

The record breaking fight of Miguel Cotto vs. Floyd Mayweather Jr. brought in more than 1.5 million pay-per-viewers, and the 18-year-old singer shared his excitement about being in attendance as he tweeted, “cinco de mayo... #MayweatherCotto yeah @FloydMayweather today is a BIG day.” Bieber followed up with the simple hashtag tweet “#FIGHTNIGHT.”

Mayweather won the fight and the “Never Say Never” singer was the first person to congratulate the boxer and acted as his guest of honor. Bieber was also joined by rappers Lil Wayne and 50 Cent after the match, which was held at the MGM Grand Garden Arena.

The victor took to Twitter to share his thanks to the teen sensation after the fight, messaging, “@justinbieber keep up the great work and thanks for the support #TheMoneyTeam. Enjoy the fight.”
