Connery, who lives in the Bahamas, has previously attracted accusations he's living as a 'tax exile' even though documents prove he's paid $5.9 million (£3.7 million) to the British government since 1997.
Blackman, who played 007's love interest Pussy Galore in the 1964 blockbuster, has now spoken out to slam Connery for accepting a knighthood while choosing to reside overseas.
She tells Britain's Seven magazine, "I disapprove of him strongly now... Because I don't think you should accept a title from a country and then pay absolutely no tax towards it. He wants it both ways. I don't think his principles are very high."
