Grammy Brunch: Jay Z Parties With Rihanna And Others (Photos)
He and his wife Beyoncé announced they were expecting twins last week.
So it is no wonder Jay Z was in the mood to celebrate as he arrived at Roc Nation's exclusive pre-Grammy brunch in LA on Saturday.
The rapper, 47, appeared to be in incredibly high spirits at the bash as he laughed and danced with a number of celebrity pals - while Beyoncé stayed at home, to rest ahead of her first pregnant performance at the awards ceremony on Sunday night.
