LeAnn Rimes’ Emotional Tribute To Whitney Houston

I have no idea how a singer can cry, then sing.  I can't even talk after I cry because my nose is so plugged!  I can't even sing, because the music moves me to tears, THEN my nose plugs up.  I grew up loving Whitney Houston's music and apparently she was a mentor to many.  Here is LeAnn Rimes' tribute to Whitney, how  she gets through it, I'll never know.
