Bloom, who has starred with and romanced some of Hollywood's greatest actors in a 60-year career, will appear next year alongside David Tennant, in his final outing as the Doctor.
"It is happening. They are filming at the moment. I have been organising her schedule," her manager in America, Marion Rosenberg, is reported to have told the Daily Mail.
