Perhaps-
Elon Musk
A World-Class industry I own (I am the CEO of it :D)
He is the CEO of Tesla motors.
More than 10 billion dollars I have collected
At least, that's what I believe so (too much money, too lazy to count)
Net worth about 20 Billion
A famous billionaire I am ,with of course, the ability to fly
He is also founder of spaceX which designs and launches rockets and spacecraft
And don't forget, a real beauty I have with me
not sure , could be about his ex wife Taluah Riley who is an actress
Seeing your earlier riddle it could also be -
Tony Stark (Iron Man)
