Celebrating the relaunch of his 40/40 club in New York City, new dad Jay-Z arrived around 11 p.m., taking ample time to greet friends and fans. Despite early rumors, Beyoncé
, who gave birth to Blue Ivy
Jan. 7, was a no-show. Also likely home with her child: Alicia Keys
. Her husband Swizz Beats arrived solo to check out the overhauled space and was spotted chatting with Jay-Z in the security-blocked VIP section. B was there in spirit though. The deejay spun blocks of her music, as well as tunes by Michael and Janet Jackson and Britney Spears
. CC Sabitha, Fabolous, Ashanti, Mob Wives
star Renee Graziano and model Selita Ebanks were also all attendance. Jay-Z left close to 2 a.m. – but not before he had a fun moment with Warren Buffett.
