The 45-year-old rapper could not stop smiling as he sat ringside 2015 Throne Boxing Fight Night in New York on Friday.
Just hours after signing super middleweight champ Andre Ward to his growing Roc Nation sports empire, the 99 Problems star was celebrating with his new recruit at his first ever boxing show as a promoter.
While boxer and the rapper may now work together, clearly they are friends as well as they both could not stop laughing as they watched the fight.
The stars turned out to celebrate Jay’s big night including his biggest musical talent Rihanna and also actor Jake Gyllenhaal.
Noticeably absent was Jay Z’s wife Beyonce who must have decided to stay home with their little one Blue Ivy.
Even without his queen by his side, Jay Z ruled supreme with the packed out the Theater at Madison Square Garden.
The star studded crowd watched on as welterweight Dusty Hernandez-Harrison protected his undefeated record in a unanimous vote over veteran Tommy Rainone.
For his big night, the rapper looked the part of business mogul meets boxing promoter wearing a black suit with a black T-shirt and a silver necklace featuring an arrow design.
After the fight ended, Rihanna made sure to congratulate the man that helped make her a star, giving him a big hug.
For the boxing, the singer dressed in a double denim ensemble wearing a pair of boyfriend fit jeans, which she cuffed at the ankle, and a long matching jacket over a white bodice.
The songstress accessorised the look with a pair of grey lace up Manolo Blahniks and Louis Vuitton bag.
Posting a picture of herself and the music label boss on Instagram, Rihanna said: ‘Big bro. jigga. congrats to our champ tonight #Dusty#RocNationBoxingCard.’
On the same day just before the big show, Andre announced he had joined Jay Z’s company via social media.
He tweeted: ‘It’s official! Happy to be part of the Roc Nation family.’
The boxer has been out of action for 14 months due to business disputes with his former promoter.
