Scherzinger empathises with Beckham

And Scherzinger admits she found the experience completely draining, and can now empathise with Beckham - whose soccer star husband David plays for Los Angeles Galaxy, and recently signed for AC Milan - because supporting a sports star partner is a lot of hard work.

She says, "It was like time stood still, like being on a giant rollercoaster.

"At times I dared not look and kept peeking through my fingers to see what was happening. I now know what Victoria Beckham goes through watching David at all those games - you get really exhausted."
