Showbiz: Beyonce and Jay-Z let loose on the dance floor

With their gorgeous baby girl Blue Ivy, immense success and huge combined fortune, Jay-Z and Beyonce have plenty to celebrate in their lives.

And the power couple had yet another achievement to revel in on Wednesday night - the launch of the rapper's new album, Magna Carta Holy Grail.

The pair were seen partying up a storm at a warehouse party in Brooklyn, New York, to honour the 99 Problems star's new musical offering.
