The 40 year-old Australian star will be packing on 5 kilos to star in the film The Reader. In the romantic comedy, Kidman will play a seductress, and will co-star with actor Ralph Fiennes.
A source close to the actress told England’s Daily Star, "She loves her new bosom, but she finds eating so much a struggle and it is making her sleepy."
The film The Reader is set in post-war Germany, and is expected to be released in theatres in December of 2008.
