Jay-Z checks out Rhianna suitors

Rap mogul Jay -Z is so protective of his protégée Rhianna, he vets men trying to get a date with the R&B singer.

Rihanna admits she had no idea her Umbrella collaborator was so protective, but trusts his judgement implicitly.

She tells website People.com: "I just found out from a mutual friend that guys will talk to Jay first before they try to approach me.

"He's very protective. Jay has my best interests in mind. If it's a good guy I know Jay won't shut him down. But if he's not, Jay will be like, 'No, no, no.'"

She adds: "I have no clue who they are and I guess I'll never know."
