Did Letterman tap Keri's ass too?

Keri Hilson performs her great song, “Knock You Down” live…and it sucks:

Jeez, her voice doesn’t sound like a voice that could naturally hit any of those notes she did in the song. She really ruined the song for me now. And what’s good with Kanye poppin her booty? First Wayne then Kanye? Is her M.O. gonna be any guy that performs with her is allowed to tap that ass? Hmmm, interestin rep she’s building. And she needs to grow her fuckin hair out!

Keri Hilson - Knock You Down

Oh yes. Keri (excellent song writer), Ne-Yo (words can’t describe his songwriting skills), and ‘Ye (better rapper than songwriter) together? That’s an instant classic. And who directed this video? Very appealing. Only thing unappealing is Keri’s short hair…it just doesn’t work for me. That bein said I still wouldn’t kick her outta bed. Speakin of short hair…is the old Kanye back?!?!? No more heartbreak? Wonderful. Can’t wait for the new album at the end of this year.
