R&B superstar Beyonce debuted the video for her latest Top 10 single, "Love On Top," Monday.  Watch the video below.  "Love On Top" is the fourth single from Beyonce's latest album, "4," which climbed back into the Top 10 on the Billboard 200 albums chart last week after Beyonce announced that she was pregnant.  The album debuted at the top of the chart when it was released in late June, and spent eight consecutive weeks in the Top 10.  The set has been certified platinum by the RIAA for having sold more than a million copies in the US alone.
