TWINS DAD-TO-BE MEGASTAR JAY Z PARTIES WITH HIS A LIST CELEB PALS WHILE PREGNANT WIFE BEYONCE RELAX

He and his wife Beyoncé announced they were expecting twins last week.

It is not a surprise, Jay Z was in high spirit to celebrate as he arrived at Roc Nation's exclusive pre-Grammy brunch in LA on Saturday.

Jay Z, 47, appeared to be in high spirits at the bash as he laughed and danced with a number of celebrity pals - while pregnant Beyoncé stayed at home, to relax ahead of her first performance at the awards ceremony on Sunday night since she announced the news on social media.

The pair were seen laughing together before exchanging a high-five as they bid each other farewell - it appeared they were celebrating both their Grammy nods and Jay Z's exciting baby news.

Jay Z dressed up for the occasion, held at the swanky Owlwood Estate, as he arrived in a three-piece suit.

The rapper then chatted with Nick Jonas and Jaden Smith, before tucking into an ice-cream with old friend P. Diddy.
