The Brit starred alongside Connery in 1964 Bond blockbuster Goldfinger and admits it was a dream come true to work with him.
Connery turns 80 on Wednesday (25Aug10) and Blackman has spoken out to pay tribute to the Oscar-winning Scottish star.
She tells British morning show GMTV, "He is the sexiest man I think I have ever met. He's fun and he is warm and he is interesting. I suppose Mr Perfect!... Working with him was an enormous pleasure.
"He is an icon, isn't he? It doesn't matter what he plays, where he goes, what he does. He has natural charisma. A very happy birthday, Sean - to the best Bond ever."
