RIHANNA-jayz-beyoncemarried.jpgRihanna says she had no idea that her mentor, rapper Jay Z, had married Beyoncé Knowles.
The couple are said to have wed in front of 40 guests in New York City on 4 April, although neither has confirmed the rumours.
'I didn't know!' Rihanna, 20, tells People at a benefit for her Believe Foundation. 'No one knew!'
Beyoncé, 26, and Jay Z, 38, are keeping tight-lipped about the wedding. The signer was spotted hiding her hand at a basketball game in Houston last week.
