YouTube hip-hop song

http://www.youtube.com/watch?v=DjaqdGbMWd0

i was watching this video and i can't find the name of the song. i like the beat and you can hear a little bit of the lyrics at the very end but i can't make it out. does anyone know? or know what she says at the end?

Sounds like it could be Kelis, but I'm not sure of that or the song.
