Floyd Mayweather Jr. Celebrates Son's Birthday, Justin Bieber and Chris Brown Spotted at the Party

Floyd Mayweather Jr. is one cool father.

Mayweather's son Koraun celebrates birthday on Nov. 16, and the undefeated boxer threw him a great birthday bash with just about only the biggest names in the entertainment industry.

"Happy birthday to Koraun, I love you champ," Mayweather wrote on Twitter.

The birthday bash was held at the Hyatt Hotel Ballroom in Valencia, California on Saturday. Some of the most notable celebrities who attended the party were Justin Bieber and Chris Brown.

Jeremy Bieber, Justin's dad, was also there. "Quite the bash, @justinbieber @chrisbrown @RebeloChris @mama_brands @FloydMayweather @Jerzee Thalcon list goes on and on, u know how to do it," Justin Bieber's dad Jeremy wrote on Twitter.

The American rapper behind the hit single Ain't Worried about Nothin French Montana was invited to perform too in the said party.

"Shout Out to French Montana for performing at my son Koraun's birthday party last night," Mayweather wrote on Instagram along with a picture of him with his kids and Montana. "He asked for 70k but I gave him 200k for coming through for me," Mayweather added. That is just so very generous of him.

Floyd certainly has more money than he can spend, and he is known for his crazy shopping sprees. He has bought luxury cars and a private jet. He is known for betting six to seven-figure bets on sporting events. We can, basically, see just how much wealthy and rich he really is, because he always posts pictures of his money on Instagram. Thus, it should not be that big of a deal if he spent a lot of cash for his son's birthday bash.

In 2012, Mayweather gave Koraun a Los Angeles Clippers-themed birthday celebration. Surely, Koraun had a blast in his 2013 birthday bash. However, we wonder which party he thinks is better.

Mayweather has four children altogether - Zion, Iyanna, Jirah, and Koraun. Often times, he brings his children to his gym when he trains.
