Zumba Fitness back on top of UK charts

Stop it. It's not funny anymore. Zumba Fitness returns to the top spot on the UK charts this week, following a two-week hiatus during which Portal 2 enjoyed the spotlight. With no significant new titles last week, the charts appear to be an energetic shuffle of the regulars.

Portal 2 sales were down 43 percent and hit second place, while Mortal Kombat dropped by 52-percent into third. Call of Duty: Black Ops moved up a spot and took fourth, likely due to the promotion of last week's "Escalation" map pack. Everything else is pretty standard -- case in point: Just Dance 2 is hanging out in tenth.

Check out the UK top ten after the break.
