Plenty of celebs headed out to the 40/40 Club last night to party with Jay-Z, Nas, Meek Mill and more.  And it was all to celebrate the release of the new NBA 2K13 video game....which happens to feature a soundtrack executive produced by Hov himself.

Pics inside of the fellas partaking in the things they love the most--drinks, video games, and more....

Jay's role in NBA 2K13 is described by the video game company's marketing VP Jason Argent as:

"... a unique fusion of basketball, music, art and entertainment, and illustrates the evolution of 'NBA 2K' into something much bigger than simply the best basketball video game series ever made.  He was obsessed with authenticity and he really wanted to add his influence early on to make the experience better." 

And Jay said in a statement he was excited to usher in a new franchise of 2K Sports games as it will be one of the biggest in the industry.

The release of NBA 2K13 has all the fellas saying "Amen".  So Meek Mill, of course, was on hand for the festivities at Jay-Z's 40/40 club last night in Manhattan.  And Nas and Jay were spotted making nice wit Hov's protege Bridget Kelly.

DJ Clue was in the mix.

Bridget and her streaked hair posed it up on the carpet with Adrienne Bailon.  Y'all know Adrienne was there front and center.

With her "Empire Girls" co-star Julissa Bermudez too.

Bow Wow was there kicking it with reality star NeNe Leakes.  His mom, Teresa, is one of NeNe's good friends by the way.

Former "Basketball Wife" Jennifer Williams kicked it with "Real Housewives of New Jersey" star Teresa Giudice.

So much for Jay dropping Kris Humphries from the team.  Glad Kanye wasn't there...

Tracey Morgan was there to act a fool.

OKC baller Kevin Durant came through.

And Jay was spotted having some fun recently over at the new Brooklyn Barclays Center.  Must be nice to lay on your own center court logo.  He's kicking off the first of 8 almost-nightly performances at the arena this weekend to celebrate the Grand Opening.

BONUS: 

Looks like Meek Mill also spent some of the night partying the night away with Meagan Good for her sister La'Miya's birthday.  Kinda love that First Lady Good is still up in the club...
