Last week, Monica returned to Twitter after shutting down her account on the social networking site in mid-October. At the time, the R&B star shared a few choice words concerning her decision. "I will no longer be on Twitter... it has also become a way for people to do malicious things, when my sole intent was to spread positivity. I love you guys, but this is better for the protection of my children, my family, fiance and fans...Take care." She now reveals that it wasn't the backlash she received from her engagement to L.A. Laker Shannon Brown that ran her off the social media site, but the fact that she was dealing with a stalker... Here's what you had to say: Indria commented via Facebook: "I've had several stalkers. Don't ever want to experience that again!" Bella wrote via Facebook: "I don't see the point of stalking people."
