I guess getting under her “umbrella” isn’t as easy as the song makes it seem! Rihanna told PEOPLE she found out from a friend that Jay-Z makes himself out to be a brick wall between her and her potential dates.

“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,” she says of her mentor, who discovered her and signed her to his Def Jam label. “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.’”

And exactly who are the guys trying to court Rihanna? “He actually never tells me. I have no clue who they are and I guess I’ll never know,” she says. The singer, admits that her busy schedule makes dating difficult, but hopes to “get a date in sometime soon.” The Barbados-born chanteuse says she prefers “tall guys who have a sense of humor, love to laugh, have a good time and good conversation,” and describes her idea of a good date as “low key, just hanging out and watching a movie.”

Aww, “big bro” Joe Camel’s lookin out for his hot little side dish! Maybe that’s why Beyonce’s been in such a PISSY mood lately! Go figure.
