Rock of Ages star Catherine Zeta-Jones revealed that she is very lazy in her real life and as soon as a film completes she leaves exercising. However, the actress loves to dance whenever she gets a chance. 'I haven't danced for a while. I work out and I have a ballet barre in my gym. But every time I do it I think, 'Why don't I do this all the time? the star told S magazine. She added, ''I get lazy so working on this film was a bit of a shock to the system. It was like 'OK, I remember those Achilles, I remember those thigh muscles'. All those elements came back and it worked out great.'' The star also said that she had loved to work with Tom Cruise in Rock of Ages. ''He's awesome. But that doesn't surprise me. Tom throws himself into every role he does so fantastically well and it shows on film. That's why he's Tom Cruise. But to see him in this film is a real treat,'' she added.
