The British beauty was initially shocked by the muted reaction to her sexy catsuit, but soon realised the on-set presence of her director husband Len Wiseman, was causing the silence.
The 32-year-old actress married the film-maker in May 2004, after they met on the set of first movie UNDERWORLD the previous year (03).
She says, "In the first one it caused quite a stir. But this time - nothing. And I thought, 'Oh my God, something terrible has happened to my a**e in the last couple of years.'
"But then I realised everyone was looking the other way out of respect for Len. They don't mind saying. 'Phwoar, nice a**e!' to you, but if your husband is standing there they go all quiet."
