The definition of Irony?

Irony - when there is a gap between what a speaker says and what is generally understood.

While working out at the gym the other day, I saw Good Charlotte's video for Lifestyles of the Rich and the Famous.

Is it just me or is the fact that someone who sang, if not, wrote these words:

Lifestyles of the rich and the famous
They're always complainin'
Always complainin'
If money is such a problem
Well they got mansions
Think we should rob them

is now having a kid with Nicole Ritchie the exact definition of irony???

Is Nicole Ritchie not the definition of :

Celebrities who want sympathy
All they do is piss and moan
Inside the Rolling Stone
Talking about
How hard life can Be

I really liked him better when he was robbing the cradle with Hilary Duff ...
