Rihanna says mentor Jay-Z is her life coach.

The 'Umbrella' singer, who was signed by the hip-hop mogul to Def Jam
Records in 2004, admits she constantly goes to Jay-Z for professional advice
but also quizzes him about her personal problems.
Rihanna, 19, said: "Jay-Z is just an amazing mentor. I always go to him if I
have a work-related problem, but I ask him about problems in my personal
life too. He's incredible. I trust him completely."
The Barbados-born star has also quashed rumors she is planning to quit pop
to be an actress.
