Jay-Z and his partners are being sued for $7 million.
Clothing designer Dwayne Walker claims in a lawsuit that he is owed money by the '99 Problems' hitmaker and his former Roc-A-Fella record label in unpaid royalties after designing their logo, which features a letter ''R'' over a vinyl disc and a champagne bottle.
Jay-Z showered Solange Knowles with birthday surprises in the early hours of Sunday morning (24.06.12).
The '99 Problems' hitmaker had been celebrating his headline set at the BBC Radio 1 Hackney Weekend music event backstage on Saturday (23.06.12) with friends and family including Solange, his wife Beyonce Knowles, Rihanna and M.I.A. but he made sure his sister-in-law's special day didn't go unnoticed as soon as the clock struck midnight.
