Singer Beyonce Knowles did it again. Not long after she willingly posed for a selfie with a member of the audience, the Queen B surprised a lucky fan on FaceTime while performing at a recent concert. Beyonce was shaking hands with her fans when she spotted a person FaceTiming with someone during her show. To every body's surprise, the singer grabbed the guy's iPhone and said hello to the stranger on the other end. We can only imagine how ecstatic the person on the other end must have been. And why not? It's not every day that you get greeted by Beyonce.
