Kylie Minogue had a few:
Shocked in my pants
Fever in my pants
The locomotion in my pants
Especially for you in my pants
I should be so lucky in my pants
Love at first sight in my pants
All the lovers in my pants
Spinning around in my pants
Come into my world in my pants
Better the devil you know in my pants
Breathe in my pants
On a night like this in my pants
I could go on, but I reckon she's already the winner...
She even had a range of pants (lingerie)...
