When Rihanna started following Chris Brown on Twitter last week, dozens of fans expressed their concern for the two, who had a very violent and public break-up.

"I never thought you would go back to him!  You better not ... you have people that look up to you e.g. young girls," the worried fan tweeted.

So what did the R&B star have to say? "It's F****n twitter, not the alter! calm down," Rihanna angrily replied, which caused the fan to tweet, "I'm not harassing Rihanna, I (heart) her ... I'm only 14-years-old!"  A remorseful Rihanna then apologized and wrote, " ... baby girl I'm sorry, I didn't mean to hurt or offend u!"

Brown has taken this opportunity to return the favor and follow Rihanna on Twitter.  It was only a few months ago that the singer had a meltdown after being questioned about his relationship with the Grammy award winning R&B artist on Good Morning America.
