Publicity reps are paid to dupe the unsuspecting public into believing whatever line they feed us. When a celebrity is in need of damage control because of persistent rumors such as he is sleeping with his manager who is old enough to be his mama - they usually resort to the manufactured relationship.
Hollywood has been faking celebrity relationships since the early days of moving pictures. Remember Rock Hudson who dated many Hollywood starlets so the public wouldn't find out that he was gay? And who can forget the totally unbelievable relationship between Ciara and Bow Wow? Honestly, who did they think they were fooling?
Now we have Rihanna, the new Hollywood IT girl who we're supposed to believe is dating the prince of R&B, Chris Brown. It would be cute if it were true, but unfortunately it isn't. Good try though, Tina.
