Jay-Z celebrated the grand opening of his new 40/40 Club Thursday night with style, grace and a lot of celebrity faces.

The Barclays Center is a new asset in entertainment and living in Brooklyn that has not only Jay’s 40/40 Club but an array of 101 luxury suites, retail shops, and multiple bars. In the months to follow it will also be the prime destination for musical acts like Justin Bieber and Lady Gaga, as well as sporting events, including The Nets and College ball.

But Thursday was Jay-Z’s night to shine as 40/40’s Grand Opening was the social event of the week. He looked as dapper as Mad Men’s Jon Hamm in a smooth fitting suit. He told the press:

“I walked around here earlier and I just seen everybody busy and at work trying to finish up and it was a great feeling. A guy stopped me in the hallway and said, ‘Man this is a great thing for New York City.’ And that’s what the whole thing was about.”

Jay wasn’t the only star there of course. Friends like Rihanna and J. Cole also showed up to show support. Other stars in attendance were former Cheetah Girl Adrienne Bailon, Angela Yee, Anthony Mandler, and Single Ladies’ Denise Vasi. One face that was clearly missing? Beyonce. She was probably home with Blue Ivy.
