Sample Maker Kirk Rothrum claims heard in the song's moans coming from his sample library. For this record Sony would not have paid him, writes TMZ .

Rothrum says artists quite often use his sound, but it always paid neatly. Britney failed because he drags the record now before the courts.

The offending samples can be heard at the beginning of the song.
