She told The Sun: "I have songs that I write sex to. One of them is the Black Eyed Peas' Sexy. That is a very sexy song.''
So Sexy is a very sexy song? We weren't sure, so we took a quick trip to Google to find out. And here's what she is talking about:
Sexy
Girl u really got me goin
Outta control
I dot know what im doin
Lets let it go
And do what we do best
Take off our clothes
We look better undressed

Yes to sex

Yes to sex
It's so much more exciting
Yes to sex

No to War
No to war
Fightin is frightning
Fightin is frightening
Yes to sex
It's so much more exciting

OK we admit it: she has a point. That is a very sexy song.
