A year ago, at the annual pre-Grammy party, Whitney Houston, the great diva（女歌手）, walked on stage and closed the evening with a brilliant performance．

Last Saturday, Houston was once again the  1  of the showcase before the Grammys, but her presence was a posthumous（死后的）one．

“The biggest devil is me． I’m either my best friend or my worst enemy,” Houston told the ABC in an interview in 2002．

In 2009, Houston staged what seemed to be a successful  7  with the album I Look To You, which debuted on top of the charts．

But hoarse voice,   8  concerts, and continuous illness–Houston’s comeback trail wasn’t smooth at all． In an interview with Oprah Winfrey in 2009, Houston confessed: “It （show business） is too much． So much to try to live up to, to try to be, and I wanted out．”

Now that Houston has finally taken a break from all the chaos, may she rest  9  ．
