I honestly think she would have been better off not even acknowledging it, because it's something almost 30 years old and trivial. Especially during a time when there was no social media or cell phones to provide receipts.
I respect her decision to address it the way she did tho. At the end of the day it's her business to tell. With Ray J acting like a complete bafoon, how can she not say something? I understand he's her brother, but the way he moves sometimes seems a bit intentional.
At the end of the day, people are going to speculate and say what they want. She's never spoke on Shyne. So him repeatedly bringing her up, gives a bit of obsessed. He's really pressed because he wants her to acknowledge him. Maybe it was a situationship that meant more to him than it did to her.
People will have moved onto something else soon enough. They have short attention spans these days.
