Beyonce's private detective keeps an eye on Jay-Z?

London: Beyonce has allegedly hired a private detective to keep an eye on her rapper husband Jay-Z .

Sources informed Grazia Magazine that the 33-year-old songstress has hired a bodyguard to watch over the American rapper and report back to the singer, the Mirror reported.

According to sources, the 45-year-old rapper is often away, and Beyonce has found it hard in the past, so keeping an eye will act as a security and reassurance for her.

Despite putting on a united front for recent outings together, sources spilled the beans to the magazine that there is trouble in paradise.
