Question: It is revealed at the start of the film that Vanessa was a Fembot the entire time. When Austin tells Basil Exposition this, he replies that they knew all along. If they knew all along, why didn't they tell him? Am I missing something here, or is it just a very poor excuse for Austin to become single again and act the way he does?
Chosen answer: It's just a random joke and an easy way for them to write out Elizabeth Hurley and bring in Heather Graham.
Question: So did Frau convert to lesbianism through the time after being straight with Dr. Evil?
Answer: It appears so since she was with Dr. Evil in 1969 and was with Unibrow (the female golfer) in the present time. She does say (after the time with Dr. Evil), that she would never love another man again - to which he replies - "That's right", referring, of course, to her future sexual preferences.
Question: Whats the music playing when Austin is running around the hotel because he has realised he is single again?
Answer: It's called "Soul Bossa Nova", by Quincy Jones.
Question: Once Austin has introduced himself to the two models, and they start photographing, what is the music that is in the background?
Answer: The music is the theme song to the TV show "Charlie's Angels".
Answer: I don't believe there is a definitive answer, primarily because Vanessa being a fembot is more-or-less just a purposely absurd joke that by very design doesn't really make any sense. (It was a way for them to do a riff on action heroes like James Bond that have a new love interest in every film.) The closest explanation you get is Basil saying "We knew all along, sadly," which might suggest she was a fembot the entire time. But I wouldn't really think too deeply about it, since it's a very tongue-in-cheek revelation.
