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.
Rihanna's brother Rorrey has revealed she used to be a geek.
The 'Where Have You Been' singer's little brother, 22, admitted that she may be the coolest person in the music industry at the moment but she was known for being extremely intelligent at school in Barbados.
