Meanwhile in Australia, Sandra Bullock was seen enjoying the continent’s winter months — yes, you read that correctly — as she promoted her latest buddy cop comedy, The Heat, in Sydney.

Over in sunny California, Gisele Bundchen and husband Tom Brady took their two kids to the Disney’s California Adventure theme park. Enjoying the warm weather, the model mom was seen in short shorts as she visited Cars Land with son Benjamin and daughter Vivian.
