During A Live Chat On The Day Of The Album’s Release P!nk Was Asked Who’s Featured At The End Of “Run” And She Replied With “A Little Girl! We Found A Really Young Girl — Butch Did Actually — To Sing On That And I Actually Wasn’t There When She Sang It Because I Can’t Handle It. I Can’t Handle Little Girls Anymore I’m Too Emotional And I Would’ve Been Crying And She Would’ve Been Uncomfortable. So I Wasn’t Allowed To Go To That.
